Human: Melanoma is a malignant neoplasm of melanocytes. Melanocytes produce the brown pigment called as melanin. Melanoma predominantly occur in the skin, but are also found in any part of the body that contains melanocytes. If skin melanoma is found early, and if it is completely removed surgically, then the chanc of cure is high. Veterinary field: Melanomas are relatively common in dog, horse, and certain breeds of swine, but less frequent in cattle and goats, and quite rare in cats and sheep. Melanomas are extremely rare in avian species. There are previous reports in fowls (1919, 1928, 1929 and 1932) emerald duck (1978), budgerigar (1991), macaroni penguin, red-tailed hawk (1996), and Humboldt penguin (1998 and 2003).
