Melanoma of glans penis and urethra: A case report and systematic review of the literature of a rare and complex neoplasm.

OBJECTIVE: To evaluate the features and prognosis of melanoma of glans penis and urethra, with the presentation of a significant case report. MATERIALS AND METHODS: A systematic literature review was performed using the MEDLINE (PubMed) and Cochrane Libraries databases to identify all cases of male mucosal melanoma reported. RESULTS: Two hundred fifty-two patients with male mucosal primary melanoma were found. Glans penis and fossa navicularis as primary site includes the 81.6% of all lesions considered. Median Breslow's depth is 2.1 mm, whereas nine in situ melanomas have been reported. At the diagnosis, the disease was at a non-localized stage in 21.4% for glans penis melanomas and 11.7% urethral lesions, respectively. The 2 and 5-year survival for glans melanoma is 62.5% and 38.4%; higher rates were observed in the 2012-2020 period (76% and 58.8%, respectively). Two-year survival for urethral melanomas is 66.7%, while 5-year survival is 12.5%. 22 patients survived over 5 years with a Breslow's depth reported always < 3.3 mm. CONCLUSION: Melanoma of the glans penis and urethra is a rare neoplasm associated with a poor prognosis, however recent reports show higher survival rates. Surgery remains the mainstay for a localized disease. Taking into account the small number of cases reported, topical imiquimod seems to be a valid non-surgical alterative for melanoma in situ. The use of immunotherapy and targeted therapy should be considered only in an adjuvant setting according to the recommendations of cutaneous melanoma; however, additional clinical data on male mucosal melanoma are needed to draw definitive conclusions.

Could EMA and cytokeratin 7 be useful in distinguishing tricholemmal carcinoma from clear-cell squamous cell carcinoma? A case series from our department and a brief review of the literature.

Tricholemmal carcinoma is a malignant cutaneous adnexal tumor showing outer root sheath differentiation, thought to be the malignant counterpart of trichilemmoma. Although the real existence of tricholemmal carcinoma continues to be a matter of debate, it has been introduced in the recently published 4th edition of World Health Organization classification of skin tumors. Herein, we evaluated whether immunohistochemistry (EMA, CK7, CK5/14, p63, p16, and Ber-EP4) supports tricholemmal carcinoma as a separate entity and whether it could be useful in this differential diagnosis. A total of 9 cases, 3 tricholemmal carcinomas and 6 clear-cell squamous cell carcinomas were evaluated on the basis of histological criteria suggested by the WHO. In our opinion, although these results need to be validated in larger series, they support tricholemmal carcinoma as a separate entity and suggest an immunohistochemical profile (clear-cell squamous cell carcinomas: EMA diffusely positive, CK7 negative; tricholemmal carcinoma: EMA negative, CK7 patchy or moderately positive) that could be useful for this differential diagnosis.

Long Term Cosmetic and Functional Results of One Stage Reconstruction for Lower Eyelid Malignant Melanoma: A Single Centre Experience of Eleven Patients.

INTRODUCTION: Eyelid malignant melanoma represents less than 1 % of all skin melanomas and approximately 1 % of all malignant neoplasms of the eyelid skin. Because of its relative rarity, there is a paucity of descriptive papers reporting only small series of reconstructed patients. The repair of eyelid defects represents a reconstructive challenge. Ideally, the reconstruction of the defect must guarantee function with tissue of the same color, texture, and thickness of that of the removed skin and at the same time avoid complications such as ectropion and lagophthalmos. MATERIALS AND METHODS: We describe a consecutive series of 11 patients affected by cutaneous melanoma of the lower lid who underwent full-thickness excision of the neoplasm and subsequent wide excision. All the patients were treated in one-stage reconstruction modality with a modified monopedicle myocutaneous flap, harvested from omolateral upper eyelid, tunneled under the lateral canthus skin and armed with a conchal auricular cartilage framework. Four patients underwent the sentinel lymph node biopsy during reconstructive procedure. No major complications were reported. In our experience, the proposed myocutaneous flap allows to obtain excellent results, both aesthetically and functionally. CONCLUSIONS: This technique has the advantage of avoiding multi-staged procedures, with respect for the oncological excision indication for head and neck melanoma, decreasing the incidence of associated major complications.

Congenital nevus comedonicus complicated by a hidradenitis suppurativa-like lesion: Report of a childhood case.

Nevus comedonicus is a rare, benign hamartoma of the pilosebaceous unit that may be isolated or part of the nevus comedonicus syndrome. Although rare in children, complication by hidradenitis suppurativa-like lesions has been described. We present a report of a 9-year-old girl in whom surgical excision was curative, with a review of the relevant literature.

Sun exposure and melanoma prognostic factors.

Previous studies have reported an association between sun exposure and the increased survival of patients with cutaneous melanoma (CM). The present study analyzed the association between ultraviolet (UV) light exposure and various prognostic factors in the Italian Clinical National Melanoma Registry. Clinical and sociodemographic features were collected, as well as information concerning sunbed exposure and holidays with sun exposure. Analyses were performed to investigate the association between exposure to UV and melanoma prognostic factors. Between December 2010 and December 2013, information was obtained on 2,738 melanoma patients from 38 geographically representative Italian sites. A total of 49% of the patients were >55 years old, 51% were men, 50% lived in the north of Italy and 57% possessed a high level of education (at least high school). A total of 8 patients had a family history of melanoma and 56% had a fair phenotype (Fitzpatrick skin type I or II). Of the total patients, 29% had been diagnosed with melanoma by a dermatologist; 29% of patients presented with a very thick melanoma (Breslow thickness, >2 mm) and 25% with an ulcerated melanoma. In total, 1% of patients had distant metastases and 13% exhibited lymph node involvement. Holidays with sun exposure 5 years prior to CM diagnosis were significantly associated with positive prognostic factors, including lower Breslow thickness (P<0.001) and absence of ulceration (P=0.009), following multiple adjustments for factors such as sociodemographic status, speciality of doctor performing the diagnosis and season of diagnosis. Sunbed exposure and sun exposure during peak hours of sunlight were not significantly associated with Breslow thickness and ulceration. Holidays with sun exposure were associated with favorable CM prognostic factors, whereas no association was identified between sunbed use and sun exposure during peak hours of sunlight with favorable CM prognostic factors. However, the results of the present study do not prove a direct causal effect of sun exposure on melanoma prognosis, as additional confounding factors, including vitamin D serum levels, may have a role.

Vulvar Reconstruction by Perforator Flaps: Algorithm for Flap Choice Based on the Topography of the Defect.

OBJECTIVE: Many techniques have been proposed to reconstruct acquired vulvar defects. In our experience, every type of vulvar defect can be repaired with 2 pedicled flaps, namely, the pedicle deep inferior epigastric perforator (DIEP) flap and the lotus petal flap (LPF). MATERIALS AND METHODS: We report our reconstructive algorithm for vulvar reconstruction, based on the topography of the defect, applied in 22 consecutive patients from 2000 to 2012. According to the proposed algorithm, DIEP flap and LPF (monolateral or bilateral type) can repair all kinds of wide vulvar defects. Surgical defects were classified as type I (IA and IB) and type II in relation to the anatomy of the defect. RESULTS: No major complications were reported in our series. All patients reported satisfactory results, both functionally and aesthetically. CONCLUSIONS: We propose an easy classification of acquired vulvar defects separating the ones consequent only to the vulvar resection, with preservation of vagina (type I), by the wider defects after vaginal and vulvar resection (type II); type I can be subclassified into defects consequent to half-vulvar resection (type IA) or to total vulvar resection (type IB). Type I defects (IA and IB) can be reconstructed with monolateral or bilateral LPF; in type II resections, we have a great wound that required more tissue to fill the pelvic dead space, so we prefer pedicle DIEP flap.

Modified bilobed flap for one-stage earlobe reconstruction: a case report.

Many techniques have been described in the literature for the reconstruction of congenital or acquired defects of the earlobe. Most techniques for earlobe reconstruction use adjacent tissue to compose a pedicled or bilobed flap, but usually require a two-stage procedure, or need a skin graft; more rarely reconstructive methods that led to a satisfactory result and a pleasant appearance in one-stage procedure have been described. We describe a personal and geometrical modification of the double-lobed flap according to Gavello's original technique, which allows to shape the anatomical curvature of the earlobe and to reduce the skin retraction without adding any scars or skin graft. In our opinion, the revisited reconstructive technique provides lots of advantages, improves aesthetical results and provides more natural appearance.

VAC therapy for wound management in patients with contraindications to surgical treatment.

The treatment of complex wounds often requires multiple surgical debridement and eventually reconstruction with skin grafts or flaps, under local or general anesthesia. When the patient's general conditions contraindicate surgical procedures, topical negative pressure with vacuum assisted closure (VAC)) device can achieve wound healing with reduction of healing time and simpler management. We treated with VAC device four patients with complex wounds and important contraindications to surgery. In all the patients, we used VAC device with common protocol of topical negative pressure. The healing was obtained in a period variable between 18 and 40 days; the results were satisfactory in three cases, one patient developed an aesthetically unpleasant scar. We present our experience to propose VAC when surgical procedures are contraindicated.

Unusual finding of benign Abrikossoff tumor by F-18 FDG-PET mimicking melanoma recurrence.

Granular cell tumor of Abrikossoff is a rare neoplasm that may occur in a wide variety of cutaneous and visceral sites. Granular cell tumor generally shows benign behavior. However, malignant outcome with metastatic spread has also been reported. Until now, no data were available on the most useful imaging approach for diagnosis and staging. We present a case of F-18 fluorodeoxyglucose positron emission tomography in Abrikossoff tumor, suggesting that F-18 fluorodeoxyglucose positron emission tomography may have a potential role in the management of this neoplasm.

Resultados a longo prazo da radioterapia nos hemangiomas da mama näo desenvolvida / Long term results of radiotherapy for hemangioma in underveloped breasts

Os autores examinaram 48 mulheres irradiadas na regiäo mamária no período infantil a fim de estabelecer os efeitos dos tipos de radiaçöes e suas doses sobre o desenvolvimento da mama e da aréola, e as mudanças cutâneas devidas à irradiaçäo. Foram encontradas leves e graves disparidades de crescimento em mais de 50//dos casos, assim como mudanças cutâneas. Esses resultados parecem ser principalmente relacionados à posiçäo do hemangioma, ao tipo de irradiaçäo e dose total recebida. No entanto, a idade na época do tratamento e o tipo de hemangioma näo parecem influenciar o resultado sucessivo
