Abstract

This case report describes the successful surgical removal and histopathology of a melanocytoma in a Jersey cross bred cow. The mass located in the skin over mid ventral abdomen was removed aseptically under general anaesthesia. The mass was 17 cm in diameter and weighed 2.7 kg. Meticulous closure techniques were employed for the surgical site to prevent seroma formation. Standard postoperative care and wound management was followed with antibiotics and analgesics. Histopathological examination revealed cells with pleomorphic nuclei and cytoplasm containing dark brown pigment, suggestive of melanin. Schmorl’s reaction showed dark bluish black melanin pigment. Postsurgical examinations on the 12th and 20th day showed proper wound healing. This study reported the occurrence of melanocytoma, a rare cutaneous tumour in a cow and highlights diagnostic and treatment considerations.
