Primary cutaneous melanomas are usually divided into three separate clinicopathologic groups: lentigo maligna melanoma (LMM), superficial spreading melanoma. (SSM), and nodular melanoma (NM). Acral lentiginous melanoma has been described as the fourth distinct subtype to denote those melanomas that arise on volar and subungual skin. This entity is said to have a radial growth phase histological...

BACKGROUND While representing only 3-4% of malignant skin tumors, cutaneous melanoma is the most aggressive and lethal. Statistical knowledge about the biological behavior of this tumor is essential for guiding daily outpatient practice and aiding public health policies. OBJECTIVES To analyze the profile of patients with cutaneous melanoma attending a pathology department in Teresina (state o...

IMPORTANCE Lentigo maligna (LM) is a clinical, pathologic, and therapeutic challenge with a higher risk of local recurrence than other types of melanoma correctly treated and also carries the cosmetically sensitive localization of head and neck. OBJECTIVE To determine whether in vivo reflectance confocal microscopy (RCM) mapping of difficult LM cases might alter patient care and management. ...

INTRODUCTION Dermoscopy is a complementary technique that has led to major advances in the diagnosis of pigmented skin lesions. The aim of this study was to describe the dermoscopic features of a series of melanomas and analyze the differences between melanomas in situ and invasive melanomas. MATERIAL AND METHODS We retrospectively recorded epidemiological, clinical, histologic, and dermoscop...

Melanoma involving the conjunctiva is extremely rare. Graver prognosis has been reported with primary conjunctival melanoma than with their cutaneous counterparts [Collin et al.: Aust N Z J Ophthalmol 1986;14:29-34]. Among conjunctival melanomas, two significant risk factors for tumour-related death have been identified: (i) age older than 55 years and (ii) unfavourable tumour location (caruncl...

IMPORTANCE Life expectancy is increasing in most developed countries, and elderly people have the highest incidence of melanoma. OBJECTIVE To identify characteristics of melanoma and its management in the elderly compared with younger patients. DESIGN, SETTING, AND PARTICIPANTS Retrospective population-based study of incident cases of primary melanoma in 1621 patients with stage I or II mel...

BACKGROUND The incidence and mortality of malignant melanoma have been rising during the past decades, the latter being due to the high invasion capacity and the metastatic potential of melanoma cells to distant organs. OBJECTIVE We investigated the distribution pattern of melanoma metastases taking into account different clinicopathological subtypes of melanoma. METHODS We studied 310 stag...

BACKGROUND With the advent of incorporating the immunoperoxidase staining technique into the processing of frozen tissue, the use of Mohs micrographic surgery (MMS) has been expanded to include several high-risk tumors such as lentigo maligna, malignant melanoma, and dermatofibrosarcoma protuberans. OBJECTIVES To thoroughly review the English medical literature pertaining to the use of immuno...
