A 6-year-old, castrated male, mixed-breed dog was diagnosed with partial unilateral ureteral obstruction secondary to a ureteral mass. The ureteral mass was surgically resected, and an ureteroneocystostomy was performed. Histopathology of the ureteral mass was consistent with a poorly differentiated mast cell tumor (MCT). The patient recovered well but was euthanized 5 months postoperatively for central nervous system signs. A choroid plexus tumor was diagnosed during necropsy examination. There was no evidence of recurrence or dissemination of the ureteral MCT. Extracutaneous MCTs are rare in dogs, and primary MCT associated with the urinary tract has not previously been reported in the veterinary literature.
一只6岁已去势的雄性混血犬被诊断为因输尿管肿物继发部分单侧输尿管梗阻。对输尿管肿物进行了手术切除，并实施了输尿管膀胱吻合术。输尿管肿物的组织病理学检查结果符合低分化肥大细胞瘤（MCT）。该犬恢复良好，但术后5个月因出现中枢神经系统症状而实施安乐死。尸检时诊断为脉络丛肿瘤。没有证据表明输尿管MCT复发或扩散。皮肤外MCT在犬中罕见，兽医文献中此前尚未报道过与泌尿道相关的原发性MCT。
