The aim of the study was to present clinical, surgical and histopathological results of the perianal neoplasia. Twenty four dogs presented at Department of Surgery Faculty of Veterinary Medicine Ankara University with perianal neoplasia were included. The breed dispersion of the dogs were Terriers (n=12), Mixed (n=4), Cocker (n=2), Boxer (n=1), Shi tzu (n=1), Collie (n=1), Tibetan spaniel (n=1) and Pekingese (n=1). The ages were between 6 and 15 years old. Two of the 23 dogs were female and the others were male. Perianal swelling, faecal tenesmus, itching, hemorrhage, pain and dyschezia were the clinical symptoms. Three of them had tumors in tail, one had in abdomen and one had in auricula in addition to perianal mass. Except for cytoreductive surgery in one cases complete resection were carried out in the operation. Orchiectomy was performed in all male dogs. Perioperative analgesia was achieved by epidural morphine preoperatively. In histopathologic examination perianal gland adenoma (n=11), hepatoid gland epithelioma (n=3), lipoma (n=2), squamose cell carcinoma (n=2), rhabdomyosarcoma (n=1), sebaseose carcinoma (n=1), fibromyosarcoma (n=1), perianal gland adenocarcinoma (n=1) and rhabdomyom (n=1). Lipoma was the histopathologic results of the females. Circular resection was carried out in 2 cases with mucocutaneous involvement. Tail amputation were performed in cases had tail neoplasia addition to perianal masses. Recurrence were seen in three cases which were diagnosed as fibromyosarcoma, sebaseose carcinoma and perianal gland adenocarcinoma and permanent faecal incontinence were seen in none of the dogs. In conclusion surgical management was found favourable in this case series.
