A 28-year-old Pinto mare was evaluated for multiple recurrences of a perianal squamous cell carcinoma. Clinical signs included lethargy, inappetence, weight loss, dyschezia, and hematochezia. The tumor involved the proximal portion of the vulvar labia, the perineum, and the anus, and there was a rectal fistula just left of the anus. Permanent end-on colostomy without further treatment of the carcinoma was the management option chosen. The colostomy functioned satisfactorily, and the mare's condition was stable for the next 14 months. Recurrence of lethargy and inappetence and development of weakness eventually necessitated euthanasia.
