Dermatofibrosarcoma is a rare skin tumor. Morphological characteristics can be misleading and unknown to most of physicians. Diagnostic delay may affect patient´s management and prognosis. We here report the case of a young patient with lesions protruding from the abdominal wall mistaken for benign cysts. X-ray examination revealed subcutaneous adipose tissue mass. This was suspected of being a fibrosarcoma. The mass was resected with a macroscopic safety margin. The anatomo-pathological study confirmed the diagnosis of dermatofibrosarcoma. Clinical and radiological follow-up examinations didn´t show any recurrence. This study highlights the importance of suspecting this rare tumor requiring specialist treatment. [ABSTRACT FROM AUTHOR]

Background: retrospective study to elucidate the epidemio-clinical and pathological characteristics, management and evolutional aspects of DFS with comparison with the data of the literature. Procedure: a thirty seven-year study of all cases of DFS. Results: Forty-nine cases of DFS (22 males and 27 females) were diagnosed. Mean age at diagnosis was 48.2 years. The tumor appeared before the age of 15 years in five patients (10%). This was a recurrence in 12% of cases. Five patients reported a history of trauma. The average delay before consultation was 5.6 years. A solitary nodule was the predominant clinical aspect of DFS (59.2%). Mean size was 4.7 cm. The tumor was mainly located on the trunk. The diagnosis of dermatofibrosarcoma protuberans was histologically confirmed in all cases. Immunohistochemical study was achieved in 34 cases and showed positive staining for CD34. The treatment consisted of large surgical excision in all patients. Four patients had revision surgery because of tumor margins. Eight cases (17.4%) presented a local recurrence after a mean delay of 12.5 months. Conclusion: DFS is a low-malignancy potential skin tumor. Treatment of choice is surgery. The main risk is tumor relapse. A long follow-up is then very important to detect it. [ABSTRACT FROM AUTHOR]

Introduction: dermatoscopy is an innovative non-invasive technique for clinical morphology of pigmented lesions and skin tumor. The purpose of our study was to highlight the morphological and dermoscopic features of basal cell carcinoma (CBC) in our study population. Methods: we conducted a prospective unicentric study over a period of 2 years. We used dermoscopy in all patients with BCC. Statistical analysis was performed using SPSS software version 17. Results: the study included 100 patients with BCC, the average age of patients was 51.87 years, with a sex ratio F/M = 0.6. BCC most commonly occurred in the face and most patients were prototype III and IV. We established conventional and non-conventional dermatoscopic criteria. Our study showed that there is a significant relationship between prototype and the degree of BCC pigmentation. Conclusion: this study highlighted the key role of dermoscopy in detecting small-sized BCC and in facilitating the diagnosis of pigmented BCC. [ABSTRACT FROM AUTHOR]

Introduction: The tumours of skin adnexal are rare and very often benign. Because of their large diversity they caused some diagnose and classification problems. They are tumours of ten mixed up with other skin tumours. The objective of this study was to study the histopathological and epidemiological profile of the benign skin adnexal tumours in Ouagadougou and to classify them according to the differenciation type in order to well know them and improve their treatment. Methodology: We conducted a retrospective study on the period of sixteen years going from 1st January 1998 to 31 December 2013. This study interested all cases of benign skin adnexal tumours histologically confirmed (diagnosed) in the three pathology laboratories of the Ouagadougou town. Results: We collected sixty cases of skin adnexal tumours on the total of 763 cases of skin tumours representing 7.8%. The benign tumours represented 86% of the adnexal tumour cases. These tumours were occurred in the relatively young age and were preferentially located on the head (cephalic) extremity. On the histological plan, the hair follicle tumours were more frequent (42.5%) followed by sweat gland tumours (30.5%) and sebaceous gland tumours (27%). Conclusion: The annex tumours are majoritary benign occurring often on the head extremity and dominated by the hair follicle tumours. [ABSTRACT FROM AUTHOR]

Skin cysts are common conditions in dermatology practice. They have varied etiologies, and while most are acquired they may also represent a genetically determined phenomenon. They can be sporadic or familial. They are easily diagnosed clinically as "cysts", but the definitive diagnosis is strictly pathological, since they are named for the type of epithelial lining, the elements seen in the walls and the elements inside. Patients with cysts consult for cosmetic concerns and for inconvenience caused by mechanical irritation or inflammation of the cyst. The lesions may proliferate and even tumors may develop from the epithelial coating. We briefly review the most important skin cysts and pseudocysts and present three clinical cases. Palabras clave: quiste; pseudoquiste; quiste epidérmico; quiste triquilemal; esteatocistoma [ABSTRACT FROM AUTHOR]

Summary: Suggest a surgical thinking for a multidisciplinary problem is inevitably difficult. Nevertheless, through targeted clinical examples, we tried to prioritize our clinical and intellectual approach for advanced tumors of the cephalic extremity. In these cases, decisions can only be collegial, and respect for the patient and his choices remain essential. Ultimately, we would argue this problematic, discussing successively the histological type, ethical concern with regard to clinic, operability and reconstruction opportunities.

Abstract: The keloid scar is a fibrous skin tumor, intradermal, and exuberant. It is commonly found on the glabrous skin. The keloid of the palms and soles are rare. Small series are reported in English literature. The authors report a case of large keloids located on both palms and soles, within a context of keloid disease, in a man of 37 years. On the left hand, the keloid scar caused a partial syndactyly IV-V. Large keloid tumors occupied the inner edge and, weight-bearing areas of both feet. These tumors rendered wearing of shoes impossible and interfered with walking. The treatment consisted of total excision of palmar and plantar keloid tumors. The residual defects were covered by a total skin graft taken from the suprapubic region. The results were satisfactory aesthetically, functionally and psychosocially. [Copyright &y& Elsevier]

Summary: Subject: Skin, the main organ of the human body, is equipped with own biomechanical characteristics, highly variable depending on intra-individual factors (location, weight status, dermatological diseases…) and interindividual (age, sex…). Despite some recent cutometric studies, our review of the literature shows that there is no currently reliable analytical model representing the biomechanical behavior of the skin. Yet, this is a central issue in dermatology surgery, especially in the treatment of skin tumors, for the proper observance of surgical margins. Patients and methods: We studied prospectively on 75 resection specimens (about 71 patient (s)), for the treatment of skin lesions tumor suspicious or known malignant or benign. Room dimensions were measured before and 5minutes after excision, leading us to calculate a ratio of retraction of the skin surface. This retraction was correlated with age, gender, tumor type, and anatomic location of the site of excision. Results: The power of retraction of the skin varies significantly by region of the body. It is maximum in the upper limb (hand excluded) and in the cervical region. At the cephalic region, skin of the ear and periorbital skin have capacities of important early retraction. Unlike the lower limb (foot excluded), the back skin of the nose and face appear to be a minimum of shrinkage. Age also seems to change on that capacity shrinkage, sex would have no influence. Conclusion: Our study confirms the variations in the ability of skin retraction based on a number of factors. In dermato-oncology, that power retraction could cause significant differences between clinical surgical margins and final pathologist margins. We believe it must be taken into account by the couple surgeon–pathologist, especially in the context of invasive and/or recurrent tumors. [Copyright &y& Elsevier]

Summary: Pilomatrixoma is a benign skin neoplasm of the hair follicle. It''s common in the pediatric population. It''s usually misdiagnosed and confused with other skin lesions. Head and neck represent the usual locations. The extremity remains an exceptional location. Through an observation of a pilomatrixoma of the leg in an adult patient treated surgically without recurrence, different diagnostic and therapeutic aspects of this pathology will be recalled.

Abstract: Merkel cell carcinoma (MCC) is a rare neuroendocrine carcinoma of the skin with features of epithelial differentiation. It occurs in older patients, appears on sun exposed areas and its incidence is increasing. The surgical excision with negative margins is the first treatment and adjuvant local irradiation now is well established but regional adjuvant (lymph nodes dissection or radiation therapy) remains discussed. MCC is chemosensitive but rarely chemocurable in patients with metastasis or locally advanced tumors. The most used therapy is platinum-based polychemotherapy. [Copyright &y& Elsevier]

Summary: The solitary fibrous tumor is a rare tumor, ubiquitous, mesenchymatous essentially affecting serosal surfaces. The location in the scalp is exceptional. We report a case of tumor in left occipital scalp discovered after recurrence of a tumor initially taken for a lipoma. The motive for consultation was mainly aesthetic. The pathological examination is the main element of diagnosis. The assumption is based on a large lumpectomy and an extended and regular clinical monitoring. The forecast is favourable with a decline of one year. However, relapses may occur in the long-term and there are malignant forms. [Copyright &y& Elsevier]

Summary: Subject: Our report concerns a large intermammary cutaneous Abrikossoff tumor on a 41-year-old female patient, which has prompted us to review the literature. Case: It was a low presternal skin tumor; CT-Scanning showed a homogeneous mass 5cm high, 4cm wide and 4cm deep. Total tumoral included the right pectoralis major muscle aponevrosis. The skin defect was closed using a V–Y local plasty. Histologial examination revealed no sign of malignity. Discussion: Abrikossoff tumors (or granular cell tumors) are rare ubiquitary tumors locating preferably in ENT and bucal cavity mucosa. They develop between 20 and 60 and more often concern women. They are overwhelmingly single and benign but on occasion multifocal or malignant. Immunohistochemistry points to a schwannian origin. Treatement is exclusively surgical. Skin closure is by direct suture, skin grafting or local plasty. The use of flaps is not advised as it may delay local recidivation diagnosis. The literature reports one single other case of chest wall location. Conclusion: Abrikossoff tumors require complete exeresis and mandatory histological examination into possible signs of malignity. The risk of recidivation warrants long-term surveillance. [Copyright &y& Elsevier]

Introduction. – Merkel cell carcinoma (MCC) is a rare skin tumor with a highly malignant nature whose appropriate treatment is still debated. Wide surgery is the treatment of choice, but the question concerning protocols for adjuvant radiotherapy or chemotherapy remains open.Patients and Methods. – A retrospective analysis of 24 cases of MCC collected over a period of 9 years was performed, focusing on clinical and histologic features, and response to treatment.Results. – There were 17 women and 7 men with a mean age of 74.3 years. The median follow up was 34 months. The annual incidence per 100,000 habitants was 0.378. The head and neck localization was predominant (54%). Fifteen (68%) of patients presented with local disease (stage I), and 32% of patients presented with regional node (stage II) or distant metastases (stage III). Patients with stage I had a 5-years overall survival rate of 73,85%. Among them, five patients (33%) developed a local or nodal recurrence, although two patients were initially treated with surgery and local post-operative radiotherapy. Patients with stage II and III demonstrated a 5-year overall survival rate of 51,43%.Discussion. – Our series illustrates the clinical characteristics of this tumor of the elderly, which is mainly located on head and neck and associated with a poor prognosis. Treatments are discussed. [Copyright &y& Elsevier]

Keloid is a benign fibroblastic tumor which is most often secondary to a scar, but it can occur spontaneously in a subject with black skin. We report the case of a 19-year old patient, electrician, presenting with giant right retroauricular mass evolving over two years. For some time, the patient has experienced a feeling of heaviness on the pavilion of the right ear. The lesion had manifested as a hard, pruritic, non-painful patch gradually increasing in size. The patient had received several topical and antiseptics treatments without any effect. He had a history of traumatic injury in the right retroauricular sulcus. A month after, pruritic hypertrophic scar occurred. Physical examination showed voluminous hard, fixed, retroauricular tumor (10 × 6 cm) with normal skin color, non-painful on movement (A). Its base was sessile. The remainder of the physical examination was normal. Ultrasound showed little vascularized skin tumor of the right retroauricular sulcus with more or less sharp margins, measuring 9 x 5 cm. Two diagnoses were suspected: post-traumatic keloid (most likely) and Darier Ferrand dermatofibrosarcoma. Biopsy was performed and histological examination showed keloid. The patient underwent intramarginal excision (B). The surgical specimens weighed 75 grams (C). The postoperative course was simple with disappearance of the feeling of heaviness.

Introduction: La survenue de tout trouble de la vision est inquiétante pour les patients qui savent généralement que le diabète peut être responsable de complications ophtalmologiques graves. Certains de ces troubles sont liés à des fluctuations de la réfraction et évoluent parallèlement à l’équilibration du diabète. Nous présentons des paralysies transitoires de l’accommodation survenant lors de l’introduction d’une insulinothérapie pour discuter de leurs mécanismes. Patients et méthodes: Quatre patients (3 hommes et 1 femme, âgés de 17 à 46 ans) ont été adressés à la consultation d’ophtalmologie pour l’apparition brutale d’une baisse d’acuité en vision de loin et en vision de près peu après l’introduction d’une insulinothérapie pour un diabète de type 1 de découverte récente. Résultats: La réfraction initiale (en équivalent sphérique) de ces patients allait de − 0,75 à +0,50 dioptries (moyenne : +0,08 ± +0,02 dioptrie). Aucun patient ne portait d’addition en vision de près. Leur acuité visuelle était de 10/10 Parinaud 2 à chaque œil. Moins de 8 jours après introduction de l’insulinothérapie, la réfraction de loin variait de +0,75 à +3,00 dioptries. De près, ces patients devaient porter une addition allant de +1,75 à +2,00 dioptries. L’examen ophtalmologique était normal. Cette paralysie de l’accommodation a persisté de 10 à 45 jours (médiane de 21 jours). Il y a eu retour à la réfraction initiale chez 3 patients, mais un patient de 46 ans est resté presbyte. Discussion: Les variations de la réfraction seraient induites par des modifications ioniques au sein du cristallin aboutissant à des changements de son indice de réfraction ou par des modifications de la courbure cornéenne. Les paralysies de l’accommodation survenant lors de la mise en route d’une insulinothérapie sont d’apparition plus rapide mais également de durée plus brève. Leur mécanisme pourrait être d’origine myogène, lié à des modifications de la concentration de potassium au niveau du muscle ciliaire. Conclusion: Les paralysies de l’accommodation survenant lors de l’introduction de l’insuline inquiètent des patients confrontés à un nouveau traitement mais sont généralement transitoires. Il faut savoir les rassurer et leur proposer des méthodes de corrections adaptées à cette courte période de gêne visuelle. [Copyright &y& Elsevier]
