A one and half year old heifer was presented with a hard mass hanging from brisket region. The mass was oval shaped, 10 x15 cm in size, pedunculated with the base at the level of carpal joint. Cytological examination revealed melanocytes with the presence of numerous blackish melanin pigments in the cytoplasm. Histopathological examination revealed that the tumor was comprised of heavily pigmented spindle shaped cells, arranged in sheets with a large nuclei and abundant granular black pigment in the cytoplasm. Following surgical removal of the mass, the animal recovered with no recurrence. Based on clinical examination, cytology and histopathological findings, the growth was diagnosed as cutaneous melanoma.
