Vulvar melanoma: report on eleven cases and review of the literature.

Context And Objective: Vulvar melanoma is a rare disease. We describe the experience of a single institution and review the literature.

Design And Setting: Retrospective study at the Department of Gynecology, Hospital do Cancer A.

Proteins involved in pRb and p53 pathways are differentially expressed in thin and thick superficial spreading melanomas.

Cutaneous melanoma is one of the leading causes of cancer-related death. Malignant transformation of epidermal melanocytes is a multifactorial process involving cell cycle and death control pathways. The purpose of this study was to analyze the immunohistochemical expression of cell-cycle-related and apoptosis-related proteins in cutaneous superficial spreading melanomas using the tissue microarray technique to further understand tumor development.

Cutaneous angiosarcoma of the head and neck: report of 23 cases from a single institution.

Background: To report a single-institution experience in the treatment of cutaneous head and neck angiosarcoma.

Study Design: Case series.

Patients And Methods: Twenty-three patients were evaluated: 12 females and 11 males.

Auricular rehabilitation by means of bone grafting from the iliac crest in combination with porous extraoral implants: a case report.

Background: Maxillofacial defects caused by cancer treatment are a huge problem affecting the quality of life of patients. Some of these deformities are minimized using facial epitheses, which need some additional retention devices like glasses or skin adhesives. The use of extraoral fixtures as bone anchorage was introduced many years ago and since then many patients were rehabilitated with better results.

Structural correlations between dermoscopic features of cutaneous melanomas and histopathology using transverse sections.

Interpretation of dermoscopic features of cutaneous melanoma is based on histologic description of perpendicular sections of the lesions that does not reflect the overview achieved by epiluminescence. We describe the utilization of transverse sections as a tool to define the histopathology of features that are the dermoscopic hallmarks of cutaneous melanoma. From a collection of 23 pigmented lesions with the dermoscopic diagnosis of cutaneous melanoma submitted for surgical excision we selected, from each specimen, one dermoscopic feature (black dots and globules, brown dots, blues dots and globules, depigmentation, broadened network, radial streams or pseudopods) that was sampled with a 4-mm punch (specimen) to obtain perpendicular and transverse sections.
