Non-Hodgkin CD30+ T-cell lymphoproliferative disease encompasses three subgroups, one of which is primary cutaneous anaplastic large T-cell lymphoma (PC-ALCL). It is distinguished by the presence of giant anaplastic cells with pleomorphism and widespread CD30 positivity. The case of a 58-year-old female is presented who reported to the Eye Department of Jinnah Post-Graduate Medical Centre (JPMC) on 18th January, 2023 with a three-month history of rapidly enlarging, non-tender, ulcerated lesion on the lower eyelid of the right eye. The histopathology report identified the lesion as CD30+ primary cutaneous anaplastic large cell lymphoma. Computed tomography (CT) scanning of the orbit revealed no extension, and positron emission tomography-computed tomography (PET-CT) showed no systemic involvement. The patient underwent surgical excision without adjuvant chemoradiation and has remained in clinical remission for five months.

The aim of work is description of new observations related to the participation of demodex in tumor morphogenesis with goal to study the example of eyelid papilloma, imagine the connection between the presence of the demodex mite and certain changes in the typical histomorphological picture of the neoplasm., Materials and Methods: Histomorphological examination covers biopsy and operative material of eye pathology with diagnosis of neoplasm (eyelid papilloma and actinic keratosis (senile keratosis, senile keratoma, solar keratosis)) were selected, with special attention paid to the presence of horn cysts. Agile methodologies were employed to manage the research workflow effectively., Results: As a result of the conducted histomorphological examination, in 24 cases (48%), patterns pathognomonic for demodectic infection were found. Such patterns, which could indicate the presence of a demodex mite, were cystic formations, as well as fragments of a dead parasite. We noted their presence not only in the tumor tissue, but also in the adjacent hair follicles, sebaceous glands, and subepidermal stroma. It is no coincidence that the authors who previously noted the presence of pigmented elements in keratopapillomas or seborrheic keratomas could not explain their origin, resorting to putting forward such fantastic assumptions as the presence of "symbiosis of melanoblasts and epithelial cells, which ensures the transfer of pigment from the first to the second"., Conclusions: Histomorphological study of serial sections allows us to see the successive stages of transformation of cavity intratissue defects created by the activity of the mite into horn cysts. Cavity defects are the main evidence of demodectic infestation. They occur in basal cell and squamous cell carcinomas, xanthomas, sebaceous adenomas, etc. tumors of the eyelids, but only in keratoacanthomas and senile keratomas they can turn into corneal cysts, which can be assumed to be due to the differentiating potential of these neoplasms.

Introduction: The COVID-19 pandemic created a requirement for reduced patient contact and reduced capacity in clinics. We previously published results of an Image-Based Eyelid Lesion Management Service (IBELMS) which was found non-inferior to traditional face-to-face clinic at diagnosing lesions and identifying eyelid malignancies. We now present first-year safety and efficacy data from this service., Methods: Data were collected retrospectively on all patients seen in NHS Greater Glasgow and Clyde eyelid photography clinics from 30 th September 2020 to 29 th September 2021, including referral source and diagnosis, time to clinic review, treatment and patient outcomes., Results: 808 patients were included in the study. Chalazion was the most common diagnoses recorded (38.4%). There was a statistically significant decrease in mean time from referral to appointment time between the first 4 months and last 4 months of the service (93 days to 22 days, p ≤ 0.0001). 266 (33%) of patients were discharged following photographs, 45 (6%) were discharged for non-attendance and 371 (46%) were booked for a minor procedure. 13 biopsy-confirmed malignant lesions were identified; only 3 had been referred as suspected malignancy. 23 patients out of 330 with at least 6 months follow up (7%) were re-referred within 6 months of treatment or discharge; however, none of them with a missed periocular malignancy., Discussion: Eyelid photography clinics effectively reduce patient waiting times and maximise clinic capacity. They accurately identify eyelid lesions including malignancies with a low re-referral rate. We propose that an image-based service for eyelid lesions is a safe and effective way of managing such patients., (© 2023. The Author(s).)

Despite rapid growth in the significance of dermoscopy in dermatological oncology, relatively little is yet known about the dermoscopic patterns of eyelid margin tumors. The aim of the study was to analyze the dermoscopic features of eyelid margin tumors. This was a retrospective, single-center, consecutive study which included clinical and dermoscopic analysis of eyelid margin tumors diagnosed at the Department of Dermatology, Venereology and Allergology at the Medical University of Gdańsk from 1 June 2016 to 31 December 2020. Dermoscopic features significantly more prevalent in malignant non-melanocytic lesions compared to benign ones were alteration in eyelash growth, structureless pink areas, starry milia-like cysts, and perpendicular vessels. In contrast, there were no dermoscopic features that occurred significantly more frequently in malignant melanocytic lesions when compared to benign ones. Basal cell carcinoma, in comparison to hidrocystoma, more commonly presented with ulceration and structureless pink areas. The main features differentiating basal cell carcinoma from dermal nevus were the presence of ulceration, alteration in eyelash growth, structureless pink and structureless white areas, and perpendicular vessels within the tumor with each of these features observed more commonly in basal cell carcinoma. Blue nevus, hemangioma, or pigmented hidrocystoma presenting exclusively with blue structureless areas may be difficult to differentiate based on dermoscopy. The study offers additional dermoscopic clues in the assessment of eyelid margin tumors. Some observations reported previously to be typical of basal cell carcinoma (e.g., linear vessels arranged perpendicularly to the eyelid margin) were documented also within the normal eyelid margin accompanying other cases, and according to our study, cannot be useful as a pathognomonic feature. In contrast, it seems that yellow structures (half-moon sign, starry milia-like cysts) may be important dermoscopic features, though further studies are needed to confirm our observations., (© 2022 Japanese Dermatological Association.)

Purpose: To report uveal melanoma (UM) metastasis to the contralateral ocular and periocular structures., Design: Retrospective study., Participants: Thirteen patients with UM metastasis to the contralateral ocular and periocular structures were included., Methods: Clinical records were reviewed retrospectively., Main Outcome Measures: The development and time to onset of contralateral ocular and periocular metastasis, systemic metastasis, and death., Results: Of the 13 000 treated UM patients, 13 patients were diagnosed with UM metastasis to the contralateral ocular and periocular structures. Mean patient age at primary UM diagnosis was 60 years (median, 60 years; range, 37-87 years). The primary uveal melanoma was in the choroid (n = 11) or ciliary body (n = 2) and was treated with brachytherapy (n = 11), proton beam radiotherapy (n = 1), or enucleation (n = 1). Systemic metastasis developed in 11 patients (85%) at a mean of 66 months (median, 34 months; range, 12-216 months) after diagnosis of the primary UM. All 11 patients (100%) showed liver metastasis and 8 patients (62%) also showed extrahepatic metastasis. The sites of metastasis to the contralateral ocular or periocular structures included the choroid in 4 patients (31%), the orbit in 7 patients (54%), and the eyelid in 2 patients (15%). One patient with eyelid metastasis demonstrated concurrent conjunctival nodule. Mean time to diagnosis of contralateral ocular or periocular metastasis was 94 months (median, 48 months; range, 9-375 months). Contralateral choroidal metastasis was multifocal in 3 of 4 patients (75%). Of 7 patients with orbital metastasis, 5 showed extraocular muscle involvement with restricted ocular motility. Treatment for contralateral choroidal metastasis included brachytherapy (n = 2), transpupillary thermotherapy (n = 1), and observation (n = 1). Treatment for contralateral periocular (orbit or eyelid) metastasis was excision (n = 5), external beam radiotherapy (n = 2), and observation (n = 2). Of 13 patients, death was documented in 11 patients at a mean of 17 months (median, 9 months; range, 3-54 months) as a result of systemic UM metastasis (n = 10) or unrelated cause (n = 1)., Conclusions: Metastasis resulting from UM to the contralateral ocular and periocular structures is rare and generally occurs in patients with disseminated metastasis. Orbital tissue is the most common site of involvement, and these patients have short life expectancy., (Copyright © 2021 American Academy of Ophthalmology. Published by Elsevier Inc.

Sebaceous cell carcinoma is well known as the "great masquerader" mimicking other benign or malignant eyelid conditions and lesions. We present a case of a middle age male presenting with a subacute left upper lid abscess who was ultimately diagnosed with malignant sebaceous cell carcinoma after incision and drainage and treatment with broad spectrum antibiotics. This case highlights the deceptive clinical and radiographic appearance of this tumor and the importance of histologic examination in atypical or refractory periorbital abscesses.

Purpose : To examine the patency or secondary obstruction of the lacrimal drainage system in patients with a peripunctal tumour. Methods : This retrospective, observational, and comparative study included 10 patients with a peripunctal tumour. Lacrimal probing and syringing in all patients and dacryoendoscopic examinations in 5 patients were performed to check for patency of the lacrimal drainage system. Tear meniscus height (TMH) was measured bilaterally in the upper and lower eyelids using anterior segment optical coherence tomography and compared in relation to the affected side using one-way ANOVA. Results : All patients did not complain of epiphora. Probing gave a hard stop and irrigation fluid passed into the nose. A patent punctum/canaliculus was also confirmed by dacryoendoscopy in all of the 5 patients. TMH was not significantly different among the sides ( P = .900). Conclusions : This study shows patency of the lacrimal drainage system in patients with a peripunctal tumour and no significant difference in TMH among the sides, resulting in absence of epiphora in all patients.

We present a case of a 13 year old girl with a diagnosis of Pleomorphic Adenoma (PA) located in the lacrimal gland of the left upper eyelid. The patient had a very satisfactory recovery after surgical excision of the tumor, with no recurrence after a two year follow-up. The clinical, radiological and histopathological characteristics of PAs are discussed., (Copyright © 2018 Sociedad Española de Anatomía Patológica. All rights reserved.)

Purpose: To determine the informative value of ultrasound biomicroscopy (UBM) with A-scan for assessment of qualitative and quantitative characteristics of eyelid tumors less than 5 mm in size., Material and Methods: The study included 25 patients (25 eyes) with eyelid tumors less than 5 mm in size. In addition to standard ophthalmic examination, complex ultrasound diagnostics including B-scan, Color Doppler imaging and UBM with A-scan were performed. The localization, size, structure of eyelid tumors and the state of perifocal tissues were evaluated. All patients underwent surgical treatment with following histological examinations of dissected tissues. Due to qualitative analysis of the studied formations and small number of included patients, there was no need in statistical analysis of the data., Results: Complex application of UBM and A-scan allowed specifying the localization, size, structure of the small-sized tumors and detecting typical echographic signs of benign or malignant properties of the pathological process. Ultrasound data (UBM and A-scan) of eyelid tumors was highly correlated to histological features., Conclusion: UBM with A-scan can be recommended for differential diagnostics of small-sized tumors and optimizing their management.

Purpose: To determine the practice patterns of ophthalmic plastic surgeons regarding the management of eyelid sebaceous carcinoma (SC)., Methods: An electronic survey was distributed to oculoplastic surgical colleagues in the Asia Pacific region requesting clinical information and treatment approaches to SC., Results: The responses from 192 respondents from the Asia Pacific region was included and analyzed in this study. For initial diagnosis, most surgeons selected incisional biopsy (55%), followed by complete excision (35%). Initial workup was mainly by palpation of lymph nodes, chest X-ray, and computerized tomography scan (CT-scan) of the orbit. Conjunctival map biopsy was done in selected cases. Sentinel lymph node biopsy (SLNB) was done mainly for tumors larger than 10 mm. Management was mainly by surgical excision (5 mm margin) combined with adjuvant therapy in some cases, with radiotherapy being the most common. Margin status was determined most frequently by frozen section as evaluated by the pathologist (57%) followed by Mohs micrographic surgery (18%). Surveillance was based mainly on physical examination alone., Conclusion: The Asia Pacific oculoplastic surgeons prefer incisional biopsy for lesions suspicious of SC prior to definitive surgery. This is in contrast to survey results previously reported in other populations. Frozen section control (done by an oculoplastic surgeon with pathology support) is most commonly used for margin control and conjunctival map biopsies are done only in selected cases. Despite the potential benefits of SLNB, access and expertise in this area is currently lacking in the Asia Pacific region.

Objective: to compare the accuracy of eyelid tumor diagnosis obtained by evaluating conventional camera images with the ones obtained by evaluating smartphone images., Methods: from January 2016 to July 2017, 36 patients underwent face-to-face external assessments and biomicroscopic examinations to establish clinical diagnoses. The lesions were photographed using Canon PowerShot SX530 HS Digital Camera (16.8 Megapixels) and Samsung GALAXY S4 smartphone camera. All lesions were resected and submitted to anatomopathological examinations. Preoperative images were sent to two specialists in eyelid diseases and then remotely analyzed. Data from in-person diagnoses and telediagnoses were compared with the gold standard of histological diagnosis., Results: the most frequent lesions were basal cell carcinoma (33.3%), actinic keratosis (19.4%), and nevus (13.9%). Kappa coefficient for the diagnosis of malignant lesion showed agreement between the two tele-evaluators in the conventional digital camera images (0.68) and in the smartphone images (0.78). The face-to-face examiner's accuracy was of 94.4%; the tele-evaluators' accuracy in the conventional digital camera images was of 83.3% and in the smartphone images varied from 80.6% to 86.1%. Comparing the in-person diagnoses with the telediagnoses (obtained by evaluating conventional digital camera images or smartphone images), there was no significant difference in the hit rates., Conclusion: for eyelid tumor telediagnosis, images obtained using smartphone camera were equivalent to those obtained using conventional digital camera.

Importance: Although the most recent American Joint Committee on cancer staging guidelines for ocular surface squamous neoplasia place a heightened emphasis on biopsy and histopathologic analysis, the interpretation and clinical relevance of these staging criteria are not always clear. We address limitations of using histopathologic analysis to predict clinical outcomes and suggest less-invasive assessments., Background: To investigate the impact of histopathologic depth of invasion on outcomes for tumours with the common presentation of multiple structure involvement., Design: Retrospective chart review at tertiary institution., Samples: Of 41 eyes with ocular surface squamous neoplasia between 2012 and 2017, 27 tumours involving multiple ocular structures clinically were included., Methods: Biopsied tumours were determined to be invasive beyond the basement membrane or non-invasive; non-biopsied tumours were clinically identified with unknown depth of invasion. Outcomes were compared using Fisher's exact or Student's t tests., Main Outcome Measures: Proportion of tumours cured, recurred and/or persisting., Results: Twelve tumours (44%) received primary excisional biopsy, 10 (37%) received chemotherapy without biopsy and 5 (19%) received chemotherapy and biopsy. Clinical diagnosis was correct in all biopsied cases. While there were no significant differences in outcomes between invasive vs non-invasive tumours or treatments, there was a trend toward larger basal diameter in recurrent tumours regardless of treatment., Conclusions and Relevance: When ocular surface squamous neoplasia tumours with similar clinical involvement were compared, histopathologic depth of invasion was not predictive of clinical outcomes. Future staging criteria may consider the potential of largest basal dimension for more accurate prognostication., (© 2018 Royal Australian and New Zealand College of Ophthalmologists.)

Introduction: Eyelid tumors can be diagnosed using various diagnostic techniques. However, capability of existing methods for determining the type and margins of the tumor at the preoperative stage remains insufficiently studied., Purpose: To improve the noncontact infrared meibography technique and determine its diagnostic capabilities for studying structural changes in meibomian glands in malignant eyelid tumors of epithelial origin., Material and Methods: The study included 49 people (66 eyelids), among which 21 (21 eyelids) with malignant eyelid tumors, 11 - with benign eyelid tumors (11 eyelids), and 17 (34 eyelids) comprised the control group. The mean age of patients was 64.8±1.56 years. Meibomian glands of the lower eyelids were photographed in infrared light. Receiver-operating characteristic (ROC) curves were constructed to estimate the sensitivity and specificity of the method., Results: Modified meibography showed 100% sensitivity and 90% specificity in the differential diagnosis of malignant and benign eyelid tumors in 32 patients. Unlike other methods, the modified meibography technique can clarify the margins of tumor growth, which is considered when planning the resection volume., Conclusion: Modified meibography can indicate the margins of tumor invasion; it can be successfully used in the differential diagnostics of malignant eyelid tumors of epithelial origin and benign eyelid tumors.

Case Report: We report a case of 70-year-old male from Sicily, who presented with a bilateral eyelid mass involving the tarsal conjunctiva, found to be Kaposi's sarcoma on histologic examination. Cutaneous and pulmonary Kaposi's sarcoma involvement was documented. The patient had no prior diagnosis of human immunodeficiency virus infection. This case was managed successfully after the completion of five cycles of chemotherapy with liposomal doxorubicin, and his eyelid, skin and pulmonary lesions disappeared., Conclusions: Location in the eyelid is a possible, though rare, initial solitary manifestation of Kaposi's sarcoma in elderly HIV-negative patients. Liposomal doxorubicin is a safe and effective treatment., (Copyright © 2018 Sociedad Española de Oftalmología. Publicado por Elsevier España, S.L.U. All rights reserved.)

An epithelioid hemangioma is a very rare lesion arising from vascular structures. We encountered 2 cases in atypical locations, one in the orbital and the other in the nasal region. We performed preoperative angiography in addition to the diagnostic imaging recommended in the literature. Angiography highlighted the lesions well, and in one case, it was possible to embolize the arterial trunk of a high-flow lesion. Angiography underscored how such lesions may differ from the vascular perspective, emphasizing the importance of histology in correct diagnosis. Management of both hemangiomas yielded good functional and cosmetic outcomes with no disease recurrence.

Introduction: Primary Apocrine adenocarcinomas (PAA) are very infrequent tumors that are often confused initially with benign lesions. Little is known about this disease and there is still much to be clarified. We present a case of PAA on the eyelid successfully treated with surgery alone and a literature review regarding what is currently described about this disease., Methods: Noncomparative, retrospective case report of a patient with PAA on the eyelid succesfully treated with surgery alone and a literautre review., Results: A 91-year-old man with a 2 months lesion on the upper left eyelid was treated with surgery alone with oncological margins of 5mm. The Hystopathology diagnosis was a PAA of the eyelid and free margins were obtained. After 12 months of follow-up, the patient does not show any signs of local recurrence or distant metastasis. A review of the literature suggests these tumors are located more frequently in the axilla (50%) and secondly in the head and neck (35%), with similar distribution in the upper (41%) and lower eyelid (45%). The most commonly used treatment is surgical excision, but radiotherapy and chemotherapy have also been used with variable results., Conclusions: PAA is a very rare and aggressive tumor. Because it is so infrequent, treatments are based on the sporadic cases encountered in the literature. As more cases are reported, more can be elucidated about the characteristics of this tumor, its behavior and best treatment choice and this may allow progress in the understanding and management of this disease.

Competing Interests: There are no conflicts of interest

Objective: To describe the clinical presentations of patients diagnosed with ocular adnexal or orbital squamous cell carcinoma (SCC), which possess features similar to feline restrictive orbital myofibroblastic sarcoma (FROMS)., Procedures: A retrospective review of adnexal and/or orbital SCC was performed. Cases were collected from the University of Georgia College of Veterinary Medicine and the Comparative Ocular Pathology Laboratory of Wisconsin (COPLOW) (1990-2016). Data included signalment, ophthalmic clinical signs, nonophthalmic history and clinical signs, clinician suspicion of FROMS, advanced imaging results, and subsequent histopathologic diagnosis. FROMS cases from the COPLOW over the same time span were reviewed and compared statistically to the SCC cases with a significance threshold of 0.05., Results: Nineteen cases (20 eyes) were identified with adnexal SCC with features similar to FROMS, including keratitis and eyelid/third eyelid restriction and/or thickening. There were no statistically significant differences between clinical findings in the SCC cases and the identified and compared FROMS cases (57 cases; 67 eyes), except for exophthalmos and/or resistance to retropulsion, which was less common in SCC cases (20%) than in FROMS cases (47.8%) (P = 0.027); and clinical or imaged presence of an overt eyelid or orbital mass, which was more common in the SCC cases (30%) than in the FROMS cases (4.5%) (P = 0.0010)., Conclusions: SCC with adnexal involvement has many features similar to FROMS. In addition to FROMS, SCC should be considered a differential diagnosis in cats with restrictive adnexal or orbital signs and corneal changes., (© 2017 American College of Veterinary Ophthalmologists.)

Introduction: Ocular invasion is extremely rare for a primary eyelid Basosquamous Carcinoma (BSC). It can however occur in neglected cases if the clinical signs are overseen and the BSC is misdiagnosed for a less aggressive skin carcinoma., Materials and Methods: A 58-year-old man suffering from an inferior eyelid BSC that had been neglected for 7 years was referred to our clinic. A local infiltration of the maxillary sinus and the contents of the orbit by the tumor was discovered, and he was managed with a left orbital exenteration and resection of the involved orbital bone. A follow up was established., Discussion: BSC is a rare type of skin malignancy which as an entity rests between Basal Cell Carcinoma (BCC) and Squamous Cell Carcinoma (SCC), and its aggressive nature is often greater than that of the BCC and the SCC. Having no specific clinical features differentiating it from other BCC types, it can only be diagnosed by an adequate biopsy. Its early diagnosis is crucial in diminishing it's recurrence rate and it's metastatic potential. The standard therapeutical approach is the complete excision of the tumor, best performed by Mohs micrographic surgery. In cases of ocular infiltration, orbital exenteration is also usually necessary., Conclusions: Suspect, rapidly growing skin lesions should alert clinicians and an adequate biopsy should be performed. Regarding BSC, prompt and complete excision along with systemic exclusion of metastases and a close follow up are necessary. Adjuvant radiotherapy and chemotherapy could be beneficial to the patients., Key Words: Basosquamous carcinoma (BSC), Basal cell carcinoma (BCC), Eyelid tumor, Ocular tissue invasion, Imiquimod, Maxillectomy, Metatypical basal cell carcinoma, Mohs micrographic surgery, Orbital exenteration, Orbit invasion, Squamous cell carcinoma (SCC), Vismodegib.

Ocular adnexal lymphoma (OAL) constitutes 8% of all extranodal lymphomas, being rare in the eyelids (5-20%). The objective was to report a case of eyelid follicular lymphoma in a young adult woman. A 35-year-old female with swelling in left lower eyelid with development for 2 months. The visual acuity was 20/20 in both eyes, the tumor mass was 3 cm wide and 1.5 cm long. The contrast-enhanced computed tomography showed a soft-tissue injury in the left lower eyelid but had no signs of local spread according to description. Grade 2 follicular lymphoma was diagnosed by biopsy. Oncological evaluation assessed positron emission tomography scan and bone marrow aspiration with negative results for systemic spread of disease. Patient started radiotherapy. This case highlights that young patients may present painless swelling lesions that may be largely underdiagnosed and should take into consideration some oncological pathologies.

Rationale: Though giant malignant tumors arising in the eyelid are rare, they often require extensive surgery for removal along with orbital exenteration. Because of this, repairing orbital defects is an important factor in the surgical strategy., Patient Concerns: Case 1 was a 78-year-old nomad man who presented in the Department of Ophthalmology with a giant tumor in his right eyelid, which had developed over three years. Clinical examination revealed a huge pigmented, nonhealing ulcerated lesion, approximately 52×44×40 mm in size. Case 2 was a 52-year old rural male complaining of a huge tumor in the right eyelid. Patient medical history revealed that the mass was initially the size of a soybean and gradually grew over 3 years to the size of a fist., Diagnoses: Histopathological examination of the tumors revealed that one was a basal cell carcinoma and the other a sebaceous gland carcinoma., Interventions: The two cases of giant malignant eyelid tumors were surgically excised using rapid frozen section margin control. Different pedicle myocutaneous flaps were used to repair the orbital skin defects., Outcomes: Postoperative follow-up showed perfect healing of the pedicle flaps and good patient compliance. The results of these cases indicate that covering exposed orbital cavities with composite pedicle mycuaneous flaps is a simple and practical strategy for orbital reconstruction. Not only does this help maintain orbital stability, but it also provides opportunities for patients to return to normal lives., Lessons: Although surgical management is often the first option for treatment of giant eyelid tumors, recurrence and mortality due to the tumors is still high after long-term follow-up. Therefore, early discovery and treatment is the best way to control the progression of giant eyelid tumors and enhance survivability.

Importance: The clinical diagnosis of conjunctival and eyelid margin tumors is challenging, and new noninvasive imaging techniques could be valuable in this field., Objective: To assess the diagnostic accuracy of handheld in vivo reflectance confocal microscopy (IVCM) for the diagnosis of eyelid margin and conjunctival tumors., Design: A prospective observational study was conducted at University Hospital of Saint-Etienne from January 2, 2011, to December 31, 2016 (inclusion of patients until December 31, 2015, and follow-up until December 31, 2016). A total of 278 consecutive patients with eyelid margin or conjunctival lesions were included. Conjunctival lesions were diagnosed with a conventional clinical examination using a slitlamp and by handheld IVCM. Final diagnoses were established by histopathologic examination for 155 neoformations suspicious for being malignant through clinical and/or IVCM examination that were excised and on follow-up of 12 months or longer for the remaining 140 lesions., Main Outcomes and Measures: Sensitivity, specificity, and positive and negative predictive values for malignant tumors of the conjunctiva and eyelid margin were calculated using clinical examination with slitlamp and handheld IVCM., Results: In the 278 patients (136 [48.9%] females; mean [SD] age, 59 [21] years), a total of 166 eyelid margin and 129 conjunctival lesions were included in the analysis. Of the 155 excised neoformations with a histopathologic diagnosis, IVCM showed higher sensitivity compared with clinical examination conducted with the slitlamp for malignant tumors of the eyelid margin (98% vs 92%) and conjunctiva (100% vs 88%). The specificity for malignant eyelid margin tumors was higher for IVCM than for slitlamp examination (74% vs 46%), but slightly less for malignant conjunctival tumors (78% vs 88%). Analysis of all neoformations (155 excised and 140 in follow-up) confirmed these differences in the diagnostic accuracy of the clinical examination and IVCM. The presence of hyperreflective Langerhans cells mimicking malignant melanocytes was the main cause for misdiagnosis of malignant conjunctival tumors with IVCM., Conclusions and Relevance: Handheld IVCM could be a useful tool for the identification of malignant conjunctival tumors. Further studies are required to confirm the usefulness of this device and identify possible features that can differentiate Langerhans cells from malignant melanocytes to prevent the misdiagnosis of melanoma using IVCM.

Merkel cell carcinoma of the eyelid is an aggressive, highly malignant tumor of the skin. Totaling approximately 0.5 % of all tumors of the eyelid, it constitutes a relatively small group of lid tumors. Nevertheless Merkel cell carcinoma is of significance to the ophthalmologist. Because of its clinical presentation it can be easily confused as a chalazion, a hordeolum or the lesser aggressive basal cell carcinoma. This often leads to delayed treatment. In this article we describe clinical aspects, which aim to help the ophthalmologist suspect Merkel cell carcinoma earlier. Additionally we outline a diagnostic and therapeutic workup taking into consideration the special anatomy of the eyelid.

Basal cell carcinomas are the most common malignant tumors of the eyelids. Patient history, clinical symptoms and signs, inspection, palpation and slit-lamp examination usually allow a working diagnosis; however, the clinical diagnosis requires histopathological confirmation and determination of the histopathological type. Squamous cell carcinomas, sebaceous gland carcinomas, melanomas and Merkel cell carcinomas can metastasize usually via the lymph vessels into the regional lymph nodes. Microscopically controlled excision of the primary tumor into healthy tissue is most commonly the first goal. Palpation and ultrasonography of the regional lymph nodes and also computed tomography (CT) with contrast enhancement and magnetic resonance imaging (MRI) for tumors with perineural sheath cell invasion are necessary to define the TNM stage. Non-surgical treatment options are becoming more popular in the further management of malignant eyelid tumors.

Purpose: To report a case with solitary circumscribed neuroma (SCN) in the palpebral conjunctiva., Methods: This is a retrospective observational case report of a 78-year-old female who showed a yellowish, smooth-surface, dome-shaped mass in the right lower palpebral conjunctiva near the punctum. The mass was completely removed under local anesthesia., Results: Pathological examination revealed that it was composed of benign spindle-shaped cells and tapering nuclei arranged in bundles. Immunocytochemical analyses for the S100, neurofilament, CD34, and epithelial membrane antigens were all positive. These pathological findings were consistent with a SCN. At the 6-month follow-up, there was no evidence of recurrence., Conclusion: This is the first case report of SCN in the palpebral conjunctiva. Although SCN had similar clinicopathological features to other benign peripheral nerve sheath tumors, including neurofibroma and schwannoma, immunocytochemical analyses were helpful for correct diagnosis of this case., (Copyright © 2016 British Contact Lens Association.

Purpose: To report a very rare eyelid mass confirmed to be a metastasis from lung adenocarcinoma., Methods: A 68-year-old man had a two-month history of a large nodule in the right upper eyelid. He was a known case of lung adenocarcinoma since 2 years without a history of systemic metastasis. He underwent further investigations including orbital imaging and biopsy of the lesion., Results: Biopsy and immunohistochemical evaluations of the eyelid lesion revealed a moderate to poorly differentiated adenocarcinoma, a similar histology to the lung lesion., Conclusions: Metastatic involvement of the eyelids is rarely seen; specifically, those associated with lung adenocarcinoma as the source have been reported extremely rare. Eyelid metastases present with various and non-specific clinical features, and therefore biopsy of suspicious or recurrent lesions is highly recommended to rule out such malignant processes.

Purpose: To evaluate the causes of ocular motility disturbances in a group of patients with orbitofacial neurofibromatosis (OFNF) with neurofibromas on the lid, brow, face, or in the orbit from infancy or early childhood., Methods: The medical records of patients with OFNF from one institution were retrospectively reviewed; selected patients were reexamined., Results: A total of 45 patients with unilateral OFNF and 4 with bilateral OFNF were included. Of these, 14 had no strabismus and relatively good vision, with no ductional abnormalities on either side despite large globes, sphenoid dysplasia, and neurofibromas in the orbit and/or cavernous sinus in many. The 8 patients with comitant strabismus also had no ductional abnormalities with a similar constellation of anatomic abnormalities, but these patients all had poor vision in at least one eye. The 27 patients with incomitant strabismus all had downward displacement of the globe and limited ductions., Conclusions: The pathologic anatomic changes associated with OFNF do not always cause ocular motility abnormalities: strabismus generally was not present when ocular motility was full and visual acuity was good. Comitant strabismus occurred in the setting of full ocular motility with reduced vision in at least one eye. Incomitant strabismus was always accompanied by reduced vision and a ductional abnormality in one or both eyes due to anatomic abnormalities of the orbit and skull., (Copyright © 2014 American Association for Pediatric Ophthalmology and Strabismus.

Purpose: To observe the curative effect of Xeloda in meibomian gland carcinoma., Methods: We treated a 53-year-old woman, who had recrudescent meibomian gland carcinoma, with Xeloda., Results: The mass was much smaller with decreased amount of overflow pus after 4 cycles of chemotherapy with Xeloda., Conclusions: Xeloda played a significant role in treating recrudescent meibomian gland carcinoma in this patient.

Purpose: To study the utility of hybrid single photon emission computed tomography / computed tomography (SPECT/CT) scan and dual-dye technique in identification of the sentinel lymph node (SLN) in patients with an advanced malignant eyelid tumor., Design: Nonrandomized prospective interventional study., Methods: setting: A tertiary eye care center. study population: Patients with an advanced malignant eyelid tumor without clinically involved regional lymph nodes. intervention: SLN biopsy was performed using dual-dye technique (a combination of radiotracer and vital blue dye) following localization by SPECT/CT. main outcome measures: Localization of SLN in the regional node basin by hybrid SPECT/CT scan; SLN identification rate using dual-dye technique; SLN positivity rate; false-negative rate; and complications, if any, of SLN biopsy., Results: Sixteen patients of biopsy-proven eyelid malignancy (7 squamous cell carcinomas [43.75%], 5 sebaceous cell carcinomas [31.25%], and 4 malignant melanomas [25%]) were included in the study. Preoperative localization of SLN was performed using SPECT/CT in 12 patients. SLN biopsy using dual-dye technique was performed in 16 patients. SPECT/CT accurately localized SLN in 11 out of 12 patients. The preauricular region was the most common site of SLN. SLN identification rates for dual-dye, radiotracer, and blue dye techniques were 100% (16/16 patients), 100% (16/16 patients), and 87.5% (14/16 patients), respectively. SLN showed metastasis in 2 patients (12.5%). On follow-up, 1 patient developed cervical lymph node metastasis, thus giving a false-negative rate of 7.14%. There were no complications associated with SLN biopsy., Conclusion: Accurate preoperative localization of SLN in relation to adjacent anatomic structures using SPECT/CT aids in intraoperative identification of SLN. SLN biopsy should be considered in patients with eyelid tumors at significant risk for metastasis who have clinically negative nodal basins. Dual-dye technique is safe and feasible in advanced eyelid tumors. Blue dye technique can be used for SLN biopsy in settings where nuclear medicine facilities are not available, albeit with a lower SLN identification rate. Detection of metastasis in SLNs in ∼12% of cases emphasizes the utility of SLN biopsy in accurate staging and treatment of eyelid malignancies., (Copyright © 2013 Elsevier Inc. All rights reserved.)

Nasopalpebral lipoma-coloboma syndrome is an extremely uncommon autosomal dominant condition characterized by congenital upper eyelid and nasopalpebral lipomas, colobomata of upper and lower eyelids, telecanthus, and maxillary hypoplasia. A few familial and sporadic cases of this malformation syndrome have been previously reported. Here, the clinical, radiological, and histopathological features of a sporadic Mexican patient with the nasopalpebral lipoma-coloboma syndrome are described. To our knowledge, this is the first time that craniofacial 3D computed tomography imaging was used for a detailed assessment of the facial lipoma., (Copyright © 2013 Wiley Periodicals, Inc.)

A 74-year-old man with right upper eyelid swell accepted FDG PET/CT examination, which showed an intensely FDG-avid soft tissue nodular mass within the eyelid. It was suggestive of malignancy. There was no evidence of active neoplastic disease elsewhere. The nodule was excised by surgery. Histopathological findings showed characteristic findings of diffuse large B-cell lymphoma. This case highlights the utility of FDG PET/CT in identifying rare types of lymphoma.

Signet-ring cell/histiocytoid carcinomas of the eyelid are rare, slow-growing, and locally aggressive tumors. They predominantly affect elderly men and clinically resemble chronic inflammatory process such as blepharitis and chalazion. To date, the histogenesis of the tumors is still controversial. Only 27 cases of primary signet-ring cell/histiocytoid carcinomas of the eyelid are published in the literature. Local recurrence and distant metastasis occur in 8 and 7 cases, respectively. We report clinical, radiographic, and pathological features of a case of signet-ring cell/histiocytoid carcinoma of the eyelid with review of relevant literature.

Purpose: The aim of this article was to describe positive sentinel lymph node biopsy (SLNB) findings in patients with periocular invasive squamous cell carcinoma (SCC)., Methods: This was a retrospective chart review of 5 patients with invasive SCC of the periocular region who underwent SLNB and were found to have regional metastasis., Results: All patients had large (2.0-4.3 cm) primary tumors with poor differentiation on pathology. In all 5 patients, SLNB was positive in the absence of other signs or evidence of regional or systemic metastasis. While tumor cells may drain to the preauricular or the submandibular basin, the preauricular lymph node was identified as the sentinel lymph node on lymphoscintigraphy in all 5 patients. With a positive sentinel lymph node, the results of SLNB changed the clinical staging and influenced subsequent treatment recommendations for each patient. We identified no complications related to SLNB including facial nerve damage, lymphedema, or allergic reaction to radioactive tracing material., Conclusions: In this series of patients with periocular invasive SCC, SLNB was well tolerated and uncovered regional metastasis in patients with no clinical signs of metastasis otherwise. The SLNB findings influenced subsequent oncologic management recommendations. The usefulness of SLNB for poorly differentiated SCC remains uncertain. Further research is necessary to establish the role of SLNB in periocular SCC.

Purpose: To assess the efficacy and safety of systemic propranolol for infantile capillary hemangiomas of the eyelid., Design: Prospective, interventional cases series., Methods: All patients with eyelid infantile capillary hemangiomas at risk of developing amblyopia seen between January 2009 and January 2012 at the University Federico II, Naples, Italy, were treated with systemic propranolol (2 mg/kg body weight per day). Maximum length of treatment was 4 months, and propranolol was suspended when complete regression of lesions was obtained or in case of collateral effects. Minimum follow-up was 6 months., Results: Of 17 patients with eyelid infantile capillary hemangiomas, 3 were excluded for asthma and 14 (7 males, 7 females; mean age, 20.85 ± 29.7 months; range, 1 to 72 months) underwent treatment with systemic propranolol. Capillary hemangiomas involved the upper eyelid in 10 cases and the lower eyelid in 4 cases. Propranolol was stopped in 1 case for hypotension and in 1 case for allergy. Treatment was administered over a mean of 2.5 ± 1.3 months (range, 1 to 4 months); the mean follow-up was 10.64 ± 8.7 months (range, 6 to 39 months). Ten patients were younger than 1 year and demonstrated complete regression. Two patients older than 5 years also benefited from treatment. In 4 cases, amblyogenic astigmatism was present and decreased from 1.25 ± 0.5 diopters before treatment to 0.25 ± 0.2 diopters after treatment. No regrowth was observed., Conclusions: Four months of treatment with oral propranolol for eyelid infantile capillary hemangiomas led to complete regression of the lesion in patients younger than 1 year. No major collateral effects were observed. Treatment also may be considered in patients older than 5 years to reduce astigmatism and for aesthetic purposes., (Copyright © 2013 Elsevier Inc.

Purpose: To evaluate the combined grey-scale ultrasonography (US) and colour Doppler imaging (CDI) as the first and primary imaging modalities in diagnosing paediatric orbital haemangiomas., Methods: The charts of 20 consecutive children with a periorbital mass echographically diagnosed as a haemangioma between January 2004 and June 2009 in the Tel-Aviv Sourasky Medical Center were reviewed. Data on demographic details, clinical findings, US and CDI characteristics, treatment and outcome were retrieved., Results: Twelve (60%) haemangiomas were located on the upper eyelid, five in the lower eyelid (25%) and three in the medial cantus (15%). The tumour resolved completely in 10 children (50%) and in 10 children (50%) partial resolution was documented. Seven (35%) patients underwent treatment (intralesional or oral steroids or propranolol). Grey-scale US depicted a solid-tissue mass with low internal echogenicity. Mean haemangioma volume was 1.33 cm(3) . Colour Doppler imaging demonstrated intralesional flow with a mean peak systolic velocity of 15.2 cm per second and a mean resistance index of 0.51. All US and CDI examinations were carried out on alert children and no sedation or general anaesthesia was needed. During mean follow-up time of 23 months, no child required any additional imaging or diagnostic procedures to confirm the diagnosis., Conclusion: Combined US and CDI are suggested as the first imaging modalities in cases with a suspected diagnosis of periocular and orbital capillary haemangioma., (© 2011 The Authors.

A 48-year-old man presented with an enlarging mass of the right upper eyelid over a 1-month period. Nine years prior, the patient was diagnosed with adenoid cystic carcinoma (ACC) of the right maxillary sinus and underwent a total maxillectomy followed by local radiotherapy. Over the previous year, the patient had been treated with chemotherapy and radiotherapy for multiple organ metastases, including the spine, chest, and oral cavity. Ophthalmic examination revealed a white, round mass on the tarsal conjunctiva of the right upper eyelid, measuring approximately 1 × 1 cm, and 2 palpable subcutaneous masses near the inferior orbital rim. Excisional biopsies of the masses were performed, and the histopathological findings were consistent with ACC with solid and cribriform patterns. Herein, the authors describe a case of metastatic ACC of the eyelid, which has not been described in the literature to their knowledge.

Rhabdomyosarcoma is a malignant mesenchymal tumor of childhood. The eyelid localization is unusual. We report the case of a 7-year-old child with upper palpebral rhabdomyosarcoma revealed by an isolated blepharoptosis. The CT-scan revealed a well delimited enhancing soft tissue mass involving the upper eyelid. The tumor was excised totally by an upper eyelid incision under general anesthesia. It was limited in preseptal eyelid without extension to the orbit. Histopathologic examination confirmed the diagnosis of embryonic rhabdomyosarcoma. Postoperatively, the upper eyelid regained its motility. The visual axis was cleared. After surgery, three cures of chemotherapy including ifosfamide, vincristine, and actinomycin were administered. After a 4 months follow up period, there was no sign of tumor recurrence.
