The present study was aimed to know the prevalence of perianal gland adenoma in canine. A total of 347 biopsy sample of dog were received by Department of Veterinary Pathology, College of Veterinary Science and Animal Husbandry, Anand during the year 2008 to 2015. The biopsy samples were subjected to histopathological examination by using H&E staining method. Out of 347 biopsy samples, the perianal gland adenoma revealed in 5.7% cases. All the cases were found in male dogs only between age group of 8 to14 years. The highest (25%) incidence was recorded at 12 years of age. It was found in most of the breed however the German shepherd was the most affected breed followed by Labrador retriever. Grossly in most of the case, single or multiple nodular mass around the anal region, perianal region, and lateral to anus was observed. Microscopically, most of the cases revealed lobules or cords of large round to polyhedral cells. The cytoplasm was abundant, acidophilic and granular. The nuclei were hyper chromatic round and centrally located. Single row of basal cells was seen at the periphery of the lobules. The pattern of neoplastic cells was identical in most of cases.
Some of the cases also revealed typical hepatoid cells and squamous metaplasia.
