Purpose: To present the long-term outcome of the Cutler-Beard two-stage technique in patients with large full-thickness upper eyelid defects after tumor excision., Methods: The medical records of 24 patients with large full-thickness upper eyelid defects reconstructed with the Cutler-Beard technique from January 2000 to January 2021 were retrospectively reviewed. All the defects involved ≥ 60% of the horizontal length of the upper eyelid and extended vertically for at least 15 mm from the eyelid margin. Patients with follow-up < 24 months were excluded. Long-term postoperative complications, functional outcome, and patient's satisfaction at the end of the follow-up were evaluated., Results: Patients' age ranged from 36 to 88 (mean 66.0  ±  10.7 years) and 58.3% were females. Seven patients (29.2%) had had previous eyelid surgeries. The most common diagnosis was basal cell carcinoma (62.5%), followed by sebaceous gland carcinoma (12.5%), squamous cell carcinoma (8.3%), and Merkel cell carcinoma (8.3%). The mean duration of follow-up was 53.0  ±  16.9 months. Eleven patients (45.8%) developed upper eyelid entropion: 9 were treated conservatively with a therapeutic contact lens, 2 patients required a third operating stage. Most patients achieved a satisfactory functional and aesthetical outcome at the end of the follow-up., Conclusions: Although non-bridging techniques are usually favored to reconstruct large upper eyelid defects, the Cutler-Beard bridge flap is a valuable technique in case of large horizontal defects where the vertical gap is greater than 15 mm. Further surgical steps are rarely necessary; however, alternative techniques should be considered following excision of highly malignant tumors., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Mohs micrographic surgery (MMS) is a highly effective treatment for skin cancers, such as squamous cell carcinoma (SCC) and basal cell carcinoma (BCC), especially in cosmetically sensitive areas. Despite its high cure rates, the procedure's impact on psychosocial outcomes, influenced by demographic, clinical, psychological, and social factors, necessitates careful consideration. This review aims to identify and synthesize the predictors of psychosocial outcomes following MMS, thereby informing patient management strategies. A comprehensive search of the PubMed database was performed to select peer-reviewed studies in English that discuss these psychosocial aspects in MMS. The review identifies younger age, female gender, smoking, centrally located facial lesions and larger operative defects as factors associated with less favorable psychosocial outcomes. Conversely, patients with strong social support and better preoperative mental health tend to experience more favorable outcomes. This highlights the utility of integrating psychological evaluations and support mechanisms into treatment plans, promoting a patient-centered approach that considers the broader health and psychosocial needs of patients. The implications of this review are significant, suggesting that focusing on these psychosocial determinants allows healthcare providers to improve patient satisfaction and overall well-being., (© 2024.

Keratinocyte carcinoma is the most common form of cancer in the United States. Often treated by surgical excision, electrodessication and curettage, or Mohs surgery, treatment can frequently leave patients with a scar and can be time consuming and inconvenient for both patients and healthcare providers. Utilizing non-ablative fractional laser therapy followed by tirbanibulin ointment, we treated 30 basal and/or squamous cell carcinomas on 23 patients over the age of 50 with varying skin types. Multiple areas of the face and body, and carcinomas at differing stages, were treated. We maximized the depth of penetration of the fractional laser by using bulk heating methods while simultaneously optimizing cosmetic results. This is an ongoing study as we continue to track the progress of our participants. Thus far, no clinical or histological recurrence of carcinoma has been found in any of the treated sites., (© 2024.

Purpose: Reconstruction of nasal defects, particularly in the lower third of the nose, presents significant challenges due to the area's complex 3-dimensional structure and thicker, more sebaceous skin. The bilobed flap, a double transposition flap, has been a popular method for addressing these nasal defects., Methods: This retrospective review examines a single surgeon's experience with bilobed flaps for nasal reconstruction over the last 15 years. Demographics, defect characteristics, intraoperative details, postoperative complications, and revisionary procedures were documented, and univariate and multivariate logistic regression analyses were used to assess complication rate associations., Results: In all, 148 bilobed reconstructions were analyzed, with a mean patient age of 62.6 years and 46.0% male prevalence. The most common indication for the procedure was basal cell carcinoma following Mohs surgery, with the majority of the defects located on the lower third of the nose. The average defect size was 1.11 cm². Complications occurred in 52.0% of cases, including pincushioning, scar thickening, asymmetry, alar stenosis, and wound dehiscence. Reoperations and additional treatments such as dermabrasion, steroid injections, and laser therapy were frequently necessary to address these issues. Logistic regression analysis demonstrated significantly more postoperative complications when the defect was located on the lower third of the nose when compared with the upper two-thirds., Conclusions: While the bilobed flap can provide adequate skin coverage with perfect color match, it is associated with notable complications that impact esthetic outcomes. Proper patient selection and surgical technique are crucial for optimizing results., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 by Mutaz B. Habal, MD.)

Purpose: Guidelines on clinical margins for basal cell carcinoma (BCC) excisions were recently published, yet the ambiguity regarding the margin continues for surgeons and pathologists. The purpose of this study was to determine the incomplete excision rate of BCC, determine the factors associated with incomplete excision, and evaluate the completeness of reporting between surgeon and pathologist., Methods: A single-center retrospective analysis was conducted on pathology reports from single excisions of BCC specimens between January 1, 2019 to December 31, 2020. The primary outcome was the incomplete excision rate (positive margins) as reported by pathologist. Logistic regression was used to determine the relationship between incomplete excision rate and anatomical location, pathologist, and surgeon. The completeness of surgeon pathology requisition forms was evaluated qualitatively., Results: Seven hundred and fifty-six pathology reports were included. The incomplete excision rate was 12% (n = 94). The most common site of incomplete excision was head and neck (n = 87, 15%), followed by trunk (n = 5, 7%), and extremities (n = 2, 2%). Five hundred and seventy-nine specimens from 6 surgeons and 9 pathologists were included in the logistic regression analysis. The Wald test showed that the location was significantly associated with incomplete excision (p < 0.05), whereas surgeon and pathologist reports were not (p > 0.05). Regarding missing information, only 47 (6%) pathology reports included "excision" in the requisition form. Four hundred and three (53%) specimens had no clinical history., Conclusions: The incomplete excision rate found in this study falls within the report range in the literature. Neither surgeon nor pathologist had significant association with incomplete excision. Incomplete excision rate of BCC may be inflated owing to the lack of standardization in requisition form and pathology reporting., (Copyright © 2024 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Background: Excision and histological examination of cutaneous neoplasms are very common diagnostic and therapeutic procedures in dermatological practice. There are often discrepancies between tissue seize in vivo and after histopathological work-up. This may raise questions according to tumor sizes or safety margins., Methods: To investigate the effect of excision and histological processing on the properties of cutaneous neoplasms in real-life 401 specimens in 324 patients were prospectively investigated. Delineated excision margins of cutaneous neoplasms were documented prior to (T0) and post excision (T1). Length, width and thickness were measured after ≥48 h of formalin fixation (T2) and after sectioning (T3) on final histological slices. Accompanying parameters such as patient age, gender, anatomical site, and tumor entity were evaluated., Results: All post-processed tissue exhibited a significant (P<0.001) median (interquartile range) reduction in length, width and thickness of 21.0% (9.5-30.0), 30.7% (20.0-40.0), and 28.0% (4.8-46.7), respectively, irrespective of site, patient age or tumor entity. Maximum median (IQR) reduction for the length and the width was observed right after excision (17.0% [4.3-25.0] and 14.0% [11.1-28.6] reduction). No significant median (IQR) tissue changes between T1 and T2 were observed (length: 4.8% (-4.3-13.3); width: 0% (-17.6-11.1); thickness 0% (-32.0-20.0). Subgroup analyses showed significantly greater tissue shrinkage in younger patients and for tissue sample sites (trunk or lower extremities)., Conclusions: Most relevant shrinkage of cutaneous samples occurs right after excision. Age- and site-depended tissue contractility can influence these effects. Formalin fixation does not affect tissue shrinkage. Smaller tissue sizes on histopathological reports are to be expected.

Background: The nose is a common site for the development of skin cancers. Mohs micrographic surgery (MMS) is a highly curative treatment for skin cancer of the nose. Reconstruction of MMS defects on the nose, especially on the distal aspect, can be challenging given the proximity of multiple subunits and limited adjacent tissue reservoirs. Our goal was to describe our experience using a nasal tip rotation flap (NTRF) for MMS defects on the distal nose., Methods: A retrospective review of all MMS cases at multiple institutions between June 2018 and June 2022 was undertaken. Cases that used an NTRF to repair the MMS defect(s) were selected, and data were collected on patient demographics, tumor type, anatomical location of the tumor, preoperative and postoperative size, number of stages needed to clear the tumor, repair dimensions, and any postoperative complications., Results: A total of 66 cases that utilized an NTRF for reconstruction were included. The mean preoperative tumor size was 0.8 cm (range: 0.3-1.6 cm), and the mean defect size was 1.2 cm (range: 0.7-1.9 cm). The defects were most commonly on the nasal tip. There were no significant complications observed., Conclusions: The nasal tip rotation flap is a reliable reconstruction option for MMS defects of the distal nose. This flap can be used for defects that involve the nasal tip, soft triangle, and/or portions of the ala, including the alar rim., (© 2024 The Authors.

We present a case of a periocular painless perifolliculitis clinically mimicking basal cell carcinoma (BCC), excised by margin-controlled excision. This case reminds readers that perifolliculitis as a response to rosacea can mimic BCC. The value of diagnostic biopsy and dermoscopy to support management planning and avoid unnecessary surgery is discussed.

Giant basal cell carcinoma (GBCC) is a rare and more aggressive variant of basal cell carcinoma. We present a case of GBCC with an overview of the challenges it presents.A man in his 60s presented to the tertiary care unit with a history of an ulcer over the posterior aspect of his left heel for the past 1 year. Examination revealed an ulceroproliferative lesion of 10×8 cm on the posterior aspect of the left heel and lower Tendo-Achilles region. A wedge biopsy of the lesion was performed twice, which demonstrated basal cell carcinoma. The patient underwent excision of the lesion with 10 mm margins. A split-thickness skin graft was placed and secured over the resultant wound with the application of a negative pressure wound dressing.The correlation between tumour size and tumour behaviour is examined. Additionally, the significance of tumour location, width of margins, incidence recurrence or metastasis is also studied., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

The internal mammary artery perforator (IMAP) flap has been widely used for chest wall and neck reconstruction. The color of its skin paddle closely resembles that of facial skin, making it attractive for facial reconstruction. However, there has been insufficient investigations reporting the use of free IMAP flap. Furthermore, even in such studies, somewhat invasive procedures, including rib cartilage resection, were employed to ensure sufficient pedicle length, potentially increasing donor morbidity. Our report presents two cases of successful facial defect reconstruction using a free IMAP flap harvested with minimal donor site damage, showing its feasibility. In the first case, a 48-year-old male underwent wide excision for a malignant melanoma on his right cheek, resulting in a 4 × 4.5 cm full-thickness defect. A free IMAP flap with a 2.5 cm pedicle, was harvested without rib cartilage resection, preserving IMA main trunk, and transferred with anastomosed to the angular vessels within the defect. The second patient presented with a 4.5 × 3.5 cm basal cell carcinoma on the left cheek, necessitating wide excision and leaving a 6 × 5 cm defect. A free IMAP flap was harvested with the same approach and successfully reconstructed the defect with connected to the superficial temporal vessels using vascular bridge. Both patients were discharged complication-free, with no recurrence during 24 and 15 months of follow-up, respectively. They were highly satisfied with the final skin color and texture outcomes. Harvesting a free IMAP flap while minimizing donor morbidity may offer an attractive option for facial reconstruction., (© 2024 Wiley Periodicals LLC.)

Surgical excision is the most effective treatment of skin carcinomas (basal cell carcinoma or squamous cell carcinoma). Preoperative assessment of tumoral margins plays a decisive role for a successful result. The aim of this work was to evaluate the possibility that hyperspectral imaging could become a valuable tool in solving this problem. Hyperspectral images of 11 histologically diagnosed carcinomas (six basal cell carcinomas and five squamous cell carcinomas) were acquired prior clinical evaluation and surgical excision. The hyperspectral data were then analyzed using a newly developed method for delineating skin cancer tumor margins. This proposed method is based on a segmentation process of the hyperspectral images into regions with similar spectral and spatial features, followed by a machine learning-based data classification process resulting in the generation of classification maps illustrating tumor margins. The Spectral Angle Mapper classifier was used in the data classification process using approximately 37% of the segments as the training sample, the rest being used for testing. The receiver operating characteristic was used as the method for evaluating the performance of the proposed method and the area under the curve as a metric. The results revealed that the performance of the method was very good, with median AUC values of 0.8014 for SCCs, 0.8924 for BCCs, and 0.8930 for normal skin. With AUC values above 0.89 for all types of tissue, the method was considered to have performed very well. In conclusion, hyperspectral imaging can become an objective aid in the preoperative evaluation of carcinoma margins., (© 2024. The Author(s).)

Background and Objectives: Basal and squamous cell carcinoma (BCC, SCC), collectively referred to as keratinocyte-derived skin cancer (KC), are the most common human cancers worldwide. Surgery is the treatment of choice, but may represent overtreatment in the very elderly. This study aims to address this issue by investigating the life expectancy of patients over 80 years after surgery., Patients and Methods: A single-center, retrospective study was performed to include surgically treated KC patients at the Department of Dermatology and Venereology of the University Hospital in St. Pölten, Austria, between 01.01.2011 and 31.12.2017, who were 80 years or older. Data on individual survival (cut-off April 30, 2020), date and cause of death were retrieved from the Austrian national demographic database at Statistics Austria (Vienna)., Results: 940 patients (450 female, 490 male, 639 BCCs, 301 SCCs) were included with 307 being alive at the cut-off date. Median postoperative survival was 57 months (95% CI, 54-63 months)., Conclusions: With a median postoperative survival of almost 5 years, surgery remains a valid treatment option for KC at the end of life. However, 77 of the treated patients died within a year after surgery and preoperative assessment might have helped to avoid overtreatment in some of these cases., (© 2024 The Author(s).

Background and Objective: The prevalence of extensive skin cancers increases with the aging of the population. Surgical management is the gold standard of curative treatment while morbidity is not negligible. There are few data in the literature concerning extensive head and neck cutaneous cancers. The aim of this article is to report our experience of curative management of head and neck extensive skin cancers., Method: In this single-center retrospective observational study, we report a series of 17 patients with extensive skin facial cancers treated by surgery between 2013 and 2022 in the maxillofacial surgery department of the Pitié-Salpêtrière Hospital. We collected clinical, therapeutic, histological, and carcinologic data., Results: The median age of the patients was 66 years [35-94]. There were 9 male and 8 women. Scalp (39 %) and cheek (22 %) locations were the most frequent ones. The most frequent histological types were squamous cell carcinoma (61 %) and basal cell carcinoma (17 %). Three patients received neoadjuvant treatment. The surgical treatment consisted mainly of carcinological resection followed by one-stage reconstruction by free flap for 5 (30 %) patients and without reconstruction for primary for 12 (70 %) patients, of whom 8 benefited from secondary reconstruction. Five patients received adjuvant radiotherapy or radio-chemotherapy. With a median follow-up of 40 months (2-72), the median overall survival was 40 months (12-72)., Conclusion: We know that extensive skin cancers of the face have a good prognosis on condition that the carcinological and reconstructive requirements are respected. Surgery remains the cornerstone of treatment while the improvement of adjuvant therapies, in particular the rise of immunotherapies or other targeted therapies, may allow to limit recurrences., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Masson SAS.

Background: Squamous cell carcinoma (SCC) is one of the most commonly diagnosed neoplastic disorders in reptiles. Recently, however, it has been demonstrated that basal cell carcinomas (BCCs) are frequently misclassified as SCCs. Several histological SCC and BCC variants have been characterised and their classification may allow the establishment of appropriate prognosis estimation and treatment approaches., Hypothesis/objectives: To describe the clinical features and surgical outcomes of SCCs and BCCs diagnosed between 2010 and 2022 in reptiles., Animals: Thirty-three captive reptiles (21 squamates and 12 chelonians)., Materials and Methods: Detailed clinical history, including staging and surgical outcomes, were performed. Statistical analysis assessed significant factors using Prism (v8.2.1)., Results: While SCC was predominantly diagnosed in lizards, BCC was most commonly diagnosed in chelonians, and both neoplasms mainly occurred in adult to aged, male individuals. Although the gross pathological findings were highly comparable between SCC and BCC, considerable variation could be seen according to the primary location (oral, cutaneous or epidermis of the shell). Humane euthanasia or noncurative intent surgeries were performed in a minority of the cases. Curative intent surgeries were successful in 19 of 27 cases during a 1- to 7-year follow-up period, yet recurrence was seen in 8 cases. The results of this study allowed the identification of significant high-risk prognostic factors for SCC and BCC in reptiles., Conclusions and Clinical Relevance: This study contributes to predicting the clinical behaviour and prognosis of distinct SCC and BCC histological variants, and selecting the most appropriate treatment protocol., (© 2024 ESVD and ACVD.)

Background: Autofluorescence (AF)-Raman microspectroscopy is a technology that can detect residual basal cell carcinoma (BCC) on the resection margin of fresh, surgically excised tissue specimens. The technology does not require tissue fixation, staining, labelling or sectioning, and provides quantitative diagnosis maps of the surgical margins in 30 min., Objectives: To determine the accuracy of the AF-Raman instrument in detecting incomplete BCC excisions during Mohs micrographic surgery (MMS), using histology as the reference standard., Methods: Skin layers from 130 patients undergoing MMS at the Nottingham University Hospitals NHS Trust (September 2022-July 2023) were investigated with the AF-Raman instrument. The layers were measured when fresh, immediately after excision. The AF-Raman results and the intraoperative assessment by Mohs surgeons were compared with a postoperative consensus-derived reference produced by three dermatopathologists. The sensitivity, specificity, and positive and negative predictive values were calculated. The study was registered with ClinicalTrials.gov (NCT03482622)., Results: AF-Raman analysis was successfully completed for 125 of 130 layers and, on average, covered 91% of the specimen surface area, with the lowest surface area covered being 87% for the eyelid and the highest being 94% for forehead specimens. The AF-Raman instrument identified positive margins in 24 of 36 BCC-positive cases [67% sensitivity, 95% confidence interval (CI) 49-82] and negative margins in 65 of 89 BCC-negative cases (73% specificity, 95% CI 63-82). Only one of 12 false-negative cases was caused by misclassification by the AF-Raman algorithm. The other 11 false-negatives cases were a result of no valid Raman signal being recorded at the location of the residual BCC due to either occlusion by blood or poor contact between tissue and the cassette window. The intraoperative diagnosis by Mohs surgeons identified positive margins in 31 of 36 BCC-positive cases (86% sensitivity, 95% CI 70-95) and negative margins in 79 of 89 BCC-negative cases (89% specificity, 95% CI 81-95)., Conclusions: The AF-Raman instrument has the potential to provide intraoperative microscopic assessment of surgical margins in BCC surgery. Further improvements are required for tissue processing, to ensure complete coverage of the surgical specimens., Competing Interests: Conflicts of interest S.V., A.K., H.C.W. and I.N. hold a patent related to Raman microspectroscopy technology.

Objective: Compared with standard excision with a two-dimensional histological examination, Mohs micrographic surgery offers a lower recurrence rate and a greater extent of healthy tissue sparing for the treatment of high-risk basal cell carcinoma (BCC). The aims of this study were to first quantify the healthy tissue spared through the micrographic technique compared to traditional surgery for high-risk tumours. Then, to speculate, through the analysis of the distal micrographic resection margin, the adequate width of safety margins for standard excision., Method: A cohort of patients with high-risk BCC was treated with Mohs surgery. Safety margins, tumours residual final breach and hypothetical standard excision safety margins areas were recorded., Results: A total of 96 patients were included. A reduction of 27.96% (95% Confidence Interval (CI): 17.90-38.02) of healthy skin removed was observed using a micrographic method compared to the standard approach. Standard excision with a 6mm safety margin was associated with 86.46% (95% CI: 79.62-93.30) of complete excision. Greater margins were not associated with a statistically significant improvement of complete excision., Conclusion: Mohs surgery should be considered the gold standard operative treatment for high-risk BCC. However, if micrographic techniques are not feasible, the standard excision with a predetermined margin of 6 mm, should be considered as the best option.

Introduction: Surgical therapy of basal cell carcinomas (BCC) is based on complete excision of the neoplasm and its immediate suitable reconstruction. The aim of this work was to evaluate the possibility of creating a reconstructive algorithm in cases of scalp BCC, depending on the amplitude of the tumor., Evidence Acquisition: A literature search was carried out using the databases of PubMed, Scopus and Cochrane., Evidence Synthesis: Based on the experiences reported in the literature, it was possible to structure a decision-making algorithm that summarizes the various steps involved in the choice of the most suitable reconstructive surgical therapy., Conclusions: The algorithm described we hope will be of reference or help to less experienced reconstructive plastic surgeons.

Background: Lasers may present an alternative treatment modality for the management of nonmelanoma skin cancer (NMSC)., Objective: To investigate lasers as a definitive treatment of NMSC., Methods: A comprehensive search was performed on MEDLINE, the Cochrane Library, and the National Institutes of Health ( www.clinicaltrials.gov ). The Preferred Reporting Items for Systematic Reviews and Meta-Analysis was used to finalize a list of relevant literature studies evaluating the role of laser therapy for NMSC. Articles published through May 1, 2023, were included., Results: The authors identified 37 studies investigating nonablative and ablative lasers alone and in combination with other lasers, noninvasive imaging, and additional modalities for the treatment of basal cell carcinomas, 10 focusing on squamous cell carcinoma in situ and 3 focusing on the treatment of both basal and squamous cell carcinomas., Conclusion: Although surgical management continues to be superior to laser therapy for the management of high-risk and cosmetically sensitive tumors, laser therapy may be an acceptable alternative for low-risk lesions on the trunk and extremities. However, further studies are needed to optimize parameters, determine maximal efficacy, and provide long-term follow-up before the adoption of laser therapy for NMSC into daily clinical practice., (Copyright © 2024 by the American Society for Dermatologic Surgery, Inc.

Tumour budding (TB) correlates with increased local invasion in various neoplasms. Certain basal cell carcinomas (BCCs) exhibit local aggressiveness. Detecting adverse prognostic factors in partial biopsies could aid in identifying cases with heightened local risk. The absolute number of TB (≤ 3 tumour cells) in excision specimens of 271 infiltrative BCCs (0: absent; 1: 1-2 foci; 2: ≥ 3 foci; 3: ≥ 10 foci), the histopathological subtype and depth of infiltration, perineural invasion, and other histological features were evaluated. A significant correlation was found between TB and both depth of infiltration (rho 0.445, p < 0.001) and perineural invasion (p = 0.009). In the multivariate analysis of depth and perineural invasion (multiple regression, stepwise), TB was identified as a significant covariate together with diameter, inflammation, and perineural invasion for the former, and depth for the latter. Conversely, no correlation existed between the WHO histological subtypes (infiltrating, sclerosing, and micronodular), and depth of infiltration or perineural invasion. This study demonstrates the value of TB as a biomarker for local invasiveness in BCC. In routine practice, a count of ≥ 3 TB foci in lesions incompletely excised or with narrow tumour-free surgical margins would be a straightforward and reproducible method to guide BCC treatment.

Mohs micrographic surgery (MMS) is a well-recognized treatment for nonmelanoma skin cancer worldwide, but Japan has lagged behind many other countries in adopting MMS. We present a series of 5 cases of MMS utilized in Japanese patients. All cases had a favorable outcome, each benefiting from MMS with a smaller final defect or a higher likelihood of cure than standard excision. Slow adaptation of MMS in Japan likely is due to a lack of familiarity with the technique, lack of a training pipeline for physicians, barriers to payment for the procedure, and misconceptions among Japanese physicians. Our case series demonstrates the utility of MMS in treating skin cancer among Japanese patients.

Purpose: The main purpose of treatment of advanced ocular surface and periocular malignant tumors is to eradicate the tumor while trying to preserve visual function and aesthetics. Our purpose is to describe the outcome of a retrospective case series of 10 patients with advanced ocular surface and periocular tumors treated surgically in first instance and then with postoperative interventional radiotherapy (IRT/Brachiterapy)., Materials and Methods: We describe the clinicopathological features, treatments and outcome, in a retrospective case series of 10 patients with advanced tumors involving ocular surface (staging ≥ T2) and eyelids (staging ≥ T3), with involvement of periocular and/or orbit tissues. Patients were first surgically treated, most of them with incomplete excision, and then underwent a post-operative interventional radiotherapy (IRT/Brachytherapy) as an alternative to more invasive and disfiguring surgical retreatment. Tumor location, risk factors, staging, histological features, and follow-up timing were analyzed., Results: Three patients had advanced eyelid basal cell carcinomas, 2 patients were diagnosed with eyelid and conjunctival squamous cell carcinomas, 3 as sebaceous carcinomas, and 2 as primary conjunctival melanomas. The mean follow-up time from IRT to last clinical follow-up was 58.6 weeks, range 28.4-168 (median 43.65, IQR 28.9-72.9). Two patients - one with ocular surface SCC, the other with conjunctival melanoma - had a local recurrence 23.4 and 40,9 weeks after IRT, respectively. An overview of the current knowledge on adjuvant or post-operative IRT is also provided., Conclusions: IRT can be considered an effective therapeutic option to avoid more invasive surgical retreatment in advanced tumors involving eyelids and ocular surface., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Autofluorescence photography can detect specific light-tissue interactions and record important pathophysiological changes associated with nonmelanoma skin cancer (NMSC), which has been ascribed to the fluorescence of an aromatic amino acid, tryptophan., Objective: To assess the impact of a novel, autofluorescence imaging (AFI) device on margin control for NMSCs before Mohs micrographic surgery (MMS) in an effort to decrease overall operating time., Methods: Before the initial stage of MMS, NMSCs were measured with a 2-mm margin as standard of care (normal margin). The tumor was then imaged with the AFI device. A 2-mm margin was drawn around the fluorescent area captured by the AFI device and was referred to as the camera margin. The tumor was excised based on the normal margin and evaluated on frozen histological section., Results: Imaging based on the AFI device resulted in appropriate recommendations for margin control in 8 of 11 tumors. Four of these tumors did not fluoresce and demonstrated a lack of tumor residuum on stage I specimen, as anticipated. There were no side effects from the AFI device., Conclusion: This is an initial pilot study that supports the use of a novel, noninvasive imaging device to help with margin assessment before MMS. On optimization, this device has potential to extend applicability to surgical excisions for tumors that do not fulfill criteria for MMS., (Copyright © 2024 by the American Society for Dermatologic Surgery, Inc.

Background: Subtotal and total lower eyelid tissue loss after tumour excision is a complex issue for reconstructive surgeons. The anterior and posterior flaps must be restored to avoid compromising the functional and aesthetic prognosis of the eye. This study used a septal chondromucosal graft for the posterior lamella and a fasciocutaneous flap pedicled on the temporal artery for the anterior lamella., Method: We conducted a 10-year monocentric retrospective study, including 18 patients who were treated using a septal chondromucosal graft with a temporal artery pedicle flap following tumour excision. We collected demographic and medico-surgical data related to flap survival, absence of ectropion, lagophthalmos and other post-operative complications. The aesthetic outcome was judged using a grading scale during the last follow-up consultation., Results: All grafts and flaps survived, whereas 2 patients required early repeat surgery (1 for ectropion and 1 for graft site haematoma). None of the patients developed lagophthalmos. Two patients had distal flap injuries that healed with local care. All patients were satisfied with the aesthetic outcome at the last follow-up visit., Conclusion: Combining a septal chondromucosal graft with a fasciocutaneous flap pedicled to the temporal artery for total lower eyelid reconstruction is a reliable method with satisfactory functional and cosmetic outcomes., (Copyright © 2024 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Background: In oculoplastic surgery, reconstruction of a large defect after the removal of a massive malignant lower lid tumor still represents a unique challenge. We will report on this case, including a presentation of the case using step ladder V-Y advancement flap., Methods: During November 2018 to March 2023, five patients of lower eyelid malignant tumor had wide resection with safety margin and reconstructed using step ladder V-Y advancement flap. The flap was used step ladder V-Y advancement flap., Results: No complications, including ectropion deformity, occurred. This flap does not sacrifice healthy skin as seen with the cheek rotation flap, and the area of dissection is very small and can be performed in a short time., Conclusions: Step ladder V-Y advancement flap is highly useful in cases that require a reconstruction of a large defect after the removal of a massive malignant lower lid tumor from viewpoints of operating time, ease of procedure, aesthetics, and complications., (© 2024.

Evaluation of basal cell carcinoma (BCC) involves tangential biopsies of a suspicious lesion that is sent for frozen sections and evaluated by a Mohs micrographic surgeon. Advances in artificial intelligence (AI) have made possible the development of sophisticated clinical decision support systems to provide real-time feedback to clinicians that could have a role in optimizing the diagnostic workup of BCC. There were 287 annotated whole-slide images of frozen sections from tangential biopsies, of which 121 contained BCC, that were used to train and test an AI pipeline to recognize BCC.
