Thoracic teratoma in a white Pekin duck (Anas platyrhinchos domesticus).
Teratomas are infrequent tumors in domestic fowl and have been rarely reported in ducks. It appears that the only case of mediastinal teratoma in a Pekin duck was observed by Alezais and Cotte in 1908. A lobulated, firm mass occupied the thorax of a 7-mo-old male white Pekin duck (Anas platyrhinchos domesticus). The tumor was composed of squamous epithelium, feather follicles, glandular epithelium, bone and cartilage, and thymus and was classified as tridermic, thoracic teratoma.
