Abstract

Vaginal tumors are the second most common types of tumor in canine female reproductive tract, and most of these tumor are diagnosed as leiomyoma. These tumors are categorized by intraluminal or extraluminal form, and tend to develop as hormone dependent manner. In this report, we describe two cases of extra-luminal form of vaginal tumor. Both tumors were located in abdominal cavity, and adhered to entire surrounding internal organs, including urinary bladder, rectum, and particularly a part of ureter. Surgical excision was performed via laparotomy without damage to the surrounding internal organs and ovariohysterectomy, as well. A diagnosis of vaginal leiomyoma was established based on histopathology.

질 종양은 개 암컷생식기에서 두 번째로 많이 발생하는 종양 중 하나이며, 대부분은 평활근종으로 보고되고 있다. 질 종양의 기원은 질의 내벽 또는 외벽 유래로 구분되며, 성호르몬의 영향을 받아 성장하는 경향이 있다. 본 증례는 질 외벽 유래의 종양으로 종양은 모두 복강 내 존재했으며, 방광 및 직장, 특히 요관과 같은 주변장기와의 유착이 확인되었다. 종양은 탐색적 개복술을 통해 주변장기의 손상 없이 제거했으며 중성화 수술 또한 동시에 시행되었다. 제거된 종양은 조직학적으로 평가 한 결과 질 평활근종으로 확인되었다.
