48 cattle with cutaneous tumours were presented for surgical excision, twelve were diagnosed clinically and histopathologically to be melanocytic tumours. A retrospective study was done to evaluate biologic behavior, outcome of surgical treatment, risk factors and pathologic features of these cutaneous melanocytic tumours. 10 out of 12 melanocytic tumours were solitary, gray to black masses in dermis or subcutis. Seven cattle were Khillar breed, three Non-descript, one HF cross and one Hallikar. One tumour was congenital and other tumours were noted between 2 to 4 years of age. Of the 12 cases only one was female. There was no predilection for a particular site as the tumours were located in different areas. Tumors varied in diameter from as small as 6 cm to as large as 22 cm at time of excision. Histopathologically seven were benign and five were malignant. Surgical excision cured all the animals and there was no recurrence up to one year of follow up.
