RESUMO
Dificuldade potencial no diagnóstico histológico de melanomas é a dificuldade em reconhecer variantes pouco frequentes de melanoma. Entre elas, as mais desafiantes incluem exemplos de melanoma desmoplásico, melanoma nevoide, o chamado "melanoma de desvio mínimo", melanomas com proeminente síntese de pigmento ou "melanoma tipo animal" e o nevo azul maligno. Os autores descrevem dois casos de melanoma tipo animal e discute-se a importância do diagnóstico diferencial clinico-histopatológico nesses casos.
ABSTRACT
A potential diagnostic pitfall in the histological assessment of melanomas is the difficulty in recognizing unusual melanoma variants. Among them, the most challenging examples comprise desmoplastic melanomas, nevoid melanomas, the so-called minimal-deviation melanoma, melanomas with prominent pigment synthesis or animal-type melanoma, and the malignant blue nevus. Two cases of animal type melanoma are reported and the importance of clinical-histopathological differential diagnosis is discussed.
