Abstract: Perianal glands are non-secretory modified sebaceous glands occurring normally around the anus of dogs. In November 2017, intact male Labrador was presented to the Veterinary clinical complex, Amritsar with a growing mass around anus and defecation problems related to the mass. On physical examination, multiple, intradermermal as well as ulcerated nodules around the anus were observed. There was also a history of hematochezia, perianal pain and colorectal obstruction with tenesmus. A complete blood cell count and biochemical profile showed an elevated total Calcium of 15.4 mg/dl and regenerative anemia. Abdominal radiograph showed prostatomegaly with a mildly compressed rectum. A perianal gland adenoma was diagnosed based on the cytology examination which revealed large cuboidal isolated epithelial cells but primarily found within adherent cell clusters. Low nuclear; cytoplasmic ratios, round nuclei, single, distinct nucleolus. Mild anisocytosis and anisokaryosis was also observed. On histopathology, trabeculae and cords of tumor cells subdivided by well vascularised connective tissue stroma was observed. The dog was treated with cyclosporine.
