An intact male white pekin duck (Anas platyrhynchos domesticus) was presented for examination because of respiratory distress and 2- to 3-month history of lameness and lethargy. Results of radiography, ultrasonography, and cytologic examination revealed a large neoplastic mass in the coelom. The duck was euthanatized, and results of necropsy revealed 2 large, lobulated masses in the coelom and a small nodule on the liver. Histopathologic examination of the large masses revealed a collision pattern testicular tumor consisting of Sertoli, seminoma, and interstitial cell components. The hepatic nodule was a metastatic lesion consistent with a Sertoli cell testicular tumor. This is the first reported case of a mixed germ cell-sex cord-stromal tumor in a duck.
一只雄性纯种北京鸭（Anas platyrhynchos domesticus）因呼吸窘迫以及2至3个月的跛行和嗜睡病史前来接受检查。放射学、超声检查和细胞学检查结果显示体腔内有一个大的肿瘤性肿块。这只鸭子被实施安乐死，尸检结果显示体腔内有2个大的分叶状肿块以及肝脏上有一个小结节。对大肿块的组织病理学检查显示为一种碰撞型睾丸肿瘤，由支持细胞、精原细胞瘤和间质细胞成分组成。肝脏结节是一个与支持细胞睾丸肿瘤一致的转移病灶。这是首例报道的鸭子混合性生殖细胞-性索-间质肿瘤病例。
