A 10-year-old female Pomeranian weighing 2.25 kg with a history of gradual weight loss and an intraabdominal mass confirmed with ultrasonography at a local hospital was referred to the Veterinary Medical Teaching Hospital, Jeju National University. Physical examination revealed abdominal distention. Blood analysis revealed hypoglycemia (57 mg/dL; reference range, 60-110 mg/dL). On abdominal ultrasonography, a heterogeneously hyperechoic mass measuring 7.51 × 10.6 cm was found at the level of the left kidney. Computed tomographic findings showed a unilateral left kidney mass with a 10-cm diameter and vessel contrast enhancement in the corticomedullary phase. Unilateral nephrectomy and ovariohysterectomy were performed because left ovary enlargement was observed during surgery. The renal mass was adjacent to the aorta and vena cava and attached to a portion of the small intestine, greater omentum, and left ovary. The mass was huge (12.5 × 10 × 7 cm) and was 16.5% of the body weight. Histopathological examination revealed renal cell carcinoma (RCC) and ovarian metastasis. After surgery, clinical signs improved remarkably, and serum glucose level returned to normal. As RCC is resistant to radiation and chemotherapy, the owner decided not to proceed with postoperative adjunctive therapies. To the best of our knowledge, this is the first case report of ovarian metastasis with huge RCC in a dog.

10년령 몸무게 3.65 kg의 암컷 포메라니안이 7개월동안 지속된 요실금, 통증배뇨 및 혈뇨를 주 증으로 진료 의뢰되었다. 환자는 좌측 전견갑 부위와 좌측 겨드랑이 부위에 종괴가 확인되었다. 신체검사 및 기본검사를 통해 방광 이행상피세포암종과 이로 인한 피하 전이로 잠정 진단 하였으며, 미톡산트론과 피록시캄을 병용한 6 cycle의 항암 치료를 실시하였다. 항암 치료 기간 동안, 방광 이행상피세포암종의 크기는 점차적으로 작아졌지만, 피하 종양의 크기는 변화가 없었으며 임상증상의 개선도 미약했다. 첫 내원 후 203일째, 3주 동안의 식욕부진과 왼쪽 뒤쪽 복벽 및 왼쪽 안쪽 허벅지에 다수의 종양을 주 증으로 다시 내원하였고, 안락사 하였다. 환자는 사후 부검과 조직병리검사를 통해 만성신장질환과 방광 이행상피세포암종의 추가적인 피하 전이로 확진되었다.
