Animal Type Melanoma
Animal type melanoma is a rare form of malignant melanoma with heavily melanized epithelioid cells and a deep periappendageal growth pattern. This entity is supposed to be similar to the so called equine melanocytic disease, a long lasting indolent form of melanoma with multiple lesions, well described in grey horses. Animal type melanoma in humans has to be distinguished from deeply pigmented nevi such as epithelioid blue nevus, deep penetrating nevus and cellular blue nevus. Its relationship, if any, to the equine disease seem fanciful to us.
