Abstract

A 14-year-old, castrated male mixed-breed dog weighing 9 kg was presented for hematuria and dysuria. Abdominal ultrasound showed unilateral hydronephrosis and hydroureter with focal thickening of the ureteral wall. Surgical exploration revealed an intraluminal mass arising from the proximal left ureter. Mass resection was performed. Histopathology of the ureteral mass was consistent with a papillary transitional cell carcinoma. The patient recovered well post-operatively, but was diagnosed with another tumor three months later, this time in the right kidney. Fine-needle aspiration cytology of the renal mass revealed an epithelial cell tumor with mesenchymal features.

14살령의 중성화 수컷 개가 혈뇨와 배뇨통으로 내원하였다. 복부초음파 검사에서 편측성 수신증과 요관 벽이 국소적으로 두꺼워진 수뇨관증이 진단되었다. 수술적 탐색으로 좌측 근위 요관에서 요관 유래의 관내 종괴가 확인되었으며, 종괴 절제술이 실시되었다. 요관 종괴는 조직학적 검사를 통해 유두상 이행세포암종으로 진단되었다. 환자는 안정적으로 회복되었으나, 수술 3개월 후 또 다른 종괴가 우측 신장에서 발견되었다. 신장 종괴에 대한 세포학적 검사 결과 간엽세포종양으로 진단되었다.
