Total body mapping comprises photographic documentation of the entire body surface followed by digital dermatoscopy of selected melanocytic lesions, aiming to compare their evolution over time and identify new lesions. As this is an exam based on comparative analysis of serial dermoscopic body images, standardization of the technique for performing total body mapping is essential. Prepared by specialists from the Brazilian Society of Dermatology, using the modified Delphi method, this article provides recommendations for carrying out total body mapping in Brazil, regarding its indications, technical aspects, and the issuing of the report., (Copyright © 2021 Sociedade Brasileira de Dermatologia.

Subungual melanoma is a rare variant of acral lentiginous melanoma that often has a poor prognosis compared with other types of melanoma. The aim of the present study is to report a case of a patient with recurrence of subungual melanoma treated with imiquimod 5%, which presented a total regression of the lesion and no recurrence for 4 years.

In vivo Confocal Microscopy is a method for non-invasive, real-time visualization of microscopic structures and cellular details of the epidermis and dermis, which has a degree of resolution similar to that obtained with histology. We present a case of cutaneous melanoma in which diagnosis was aided by confocal microscopy examination. We also correlate the observed features with the dermoscopic and histopathological findings. Confocal microscopy proved to be an useful adjunct to dermoscopy, playing an important role as a method 'between clinical evaluation and histopathology'.

Pigmented epithelioid melanocytoma (PEM) is a term proposed by Zembowicz et al to encompass a rare low-grade melanocytic tumor very similar to lesions previously designated as epithelioid blue nevus and animal-type melanoma. PEM consists clinically of epithelioid, pleomorphic, atypical cells with heavy pigmentation[[1]] and histopathological studies have demonstrated a dermal proliferation of heavily pigmented melanocytes, both dendritic and spindle/epithelioid, admixed with melanophages.[3] The entity frequently presents regional lymph node involvement. The term PEM encompasses a rare low-grade melanocytic tumor with frequent regional lymph node involvement. [Extracted from the article]
