Plain-English summary
A male Pekin duck was brought in because he was having trouble breathing and had been limping and lethargic for the past 2 to 3 months. Tests showed a large tumor in his abdomen, and unfortunately, the duck was euthanized. A closer examination revealed two large tumors in his abdomen and a small nodule on his liver, which was a sign that the cancer had spread. This case is notable as it is the first reported instance of this type of testicular tumor in a duck.

Abstract
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.
