A five years old Non-descript bullock was brought to the veterinary dispensary vadamathimangalam, Thiruvannamalai District, Tamil Nadu with a history of oral mucous membrane swelling. Clinical examination revealed about 2cm diameter black colored mass was observed below the last incisor of left lower jaw region. The mass was removed by surgical intervention and sent to Department of Veterinary Pathology, Madras Veterinary College, Chennai- 600007 for histopthological examination. Grossly the mass was about 2cm in diameter, spherical black colored firm nodule with smooth surface. Microscopical examination revealed single to nest of neoplastic cells in the epithelium and lamina propria portion of the gingiva. The neoplastic cells were round to polygonal shaped cells with abundant cytoplasm contained brown black colored melanin pigment granules. Fontana silver impregnation method revealed the presence of black colored melanin pigment granules. The specific immunohistochemistry marker Melan-A was performed and showed strong expression in the neoplastic cell cytoplasm. Based on all the above finding the oral mass was confirmed as melanoma and it might be caused by sun exposure.
