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.
一匹28岁的品托母马因肛周鳞状细胞癌多次复发而接受评估。临床症状包括嗜睡、食欲不振、体重减轻、排便困难和便血。肿瘤累及外阴唇近端、会阴和肛门，肛门左侧有一个直肠瘘。选择的治疗方案是永久性端侧结肠造口术，不再进一步治疗癌症。结肠造口术功能良好，母马在接下来的14个月里状况稳定。嗜睡和食欲不振的复发以及虚弱的发展最终导致了安乐死。
