MARQUES, Mariângela Esther Alencar; YAMASHITA, Thamy; MARQUES, Silvio Alencar  y  NAI, Gisele Alborghetti. Animal type melanoma: a report of two cases. J. Bras. Patol. Med. Lab. [online]. 2010, vol.46, n.4, pp.323-328. ISSN 1678-4774.

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.
