Teixeira, Vera; Interna do Internato Complementar de Dermatologia e Venereologia/Resident, Dermatology and VenereologyIntroduction: Squamous cell carcinoma of the scrotum is a rare tumour. It was the first cancer directly linked to occupational exposure to carcinogens (polycyclic aromatic hydrocarbons).Clinical Case: A 59-year old man was referred with a one year history of a painful scrotal ulcer, 8 cm in diameter, associated with genital lymphedema. Histological examination confirmed the diagnosis of squamous cell carcinoma....
DERMATOFIBROSARCOMA PROTUBERANS IN PEDIATRIC AGE
Dermatofibrosarcoma protuberans is a rare fibrohistiocytic tumor with frequent locoregional recurrences and a low metastatic ability. Only 6% of dermatofibrosarcoma protuberans are diagnosed in children. The gold standard treatment is the surgical excision and the lower recurrence rates are observed with wide surgical margins (2,5cm) or with margin control by Mohs micrographic surgery. The authors report the ca...
DOUBLE OPPOSING RHOMBOIDAL FLAP FOR RECONSTRUCTION OF LARGE SURGICAL DEFECT OF ...
Andrade, Pedro; Interno do Internato Complementar de Dermatologia e Venereologia/Resident, Dermatology and VenereologyThe lips, as moving structures of the face, are cosmetically and functionally important areas. Closure of surgical defects involving the oral commissures is particularly challenging, due to the high risk of local anatomy disruption and functional or esthetical compromise. We describe the case of a 69-year old patient who was observed with a large basal cell carcinoma of the right perioral region, extending to t...

Pereira, Neide; Interna do Internato Complementar de Dermatologia e Venereologia/Resident, Dermatology and VenereologyA 77-year-old female patient submitted to excision of a basal cell carcinoma, resulting in an oval shaped defect with 20x25mm in diameter and exposure of the medial portions of alar cartilages. The reconstruction was perfor- med with transposition of muscle flaps from nasalis muscle in order to obtain a suitable vascular bed for a full-thickness skin graft harvested from a glabelar fold. The final result was co...
