A teratoma in a Muscovy duck ( Cairina moschata ).
Radiographic and ultrasonic examination of a sick, 5-month-old female domestic Muscovy duck revealed a large ill-defined mass in the abdominal cavity. Gross and histopathological examination characterized the mass as an intra-abdominal teratoma based on the presence of a variety of different epithelial and mesenchymal tissues, including squamous epithelium, tubular structures, feather follicles, cartilage and small amounts of osseous tissues.
