Melanoacanthoma in a Dog: A Case Report

Abstract

Sharif MAM, Eldaghayes IM, Kammon AM and Dayhum AS

A cutaneous melanoacanthoma on the forehead of a 5-year-old male mongrel dog was characterized by the presence of two populations of neoplastic cells: epithelial and melanocytic. The epithelial component consisted of nests of well-differentiated stratified squamous epithelium closely associated with neoplastic melanocytes. According to our survey, three cases of this rare pigmented skin neoplasm of the dog have been published. We present here the histological features of the fourth case of Melanoacanthoma in dogs. This report confirms the benign nature of this tumor and adds to the data that will help determine predilections of age, breed, sex and site of its occurrence.
