Avian Pathol.: Extragonadal teratoma in a domestic turkey (Meleagris gallopavo domestica).
This is the first report of a primary, spontaneous, and, most probably, congenital teratoma in a domestic turkey, localized in front of the left eyeball. The unique localization allowed surgical excision of the tumor. The histopathological examination revealed that the tumor included structures derived from all 3 germ cell layers: ectoderm, mesoderm, and endoderm (eg, cartilaginous, osseous, hematopoietic, fibrous, nervous, glandular, squamous epithelial, and smooth muscle tissues). The presence of epithelial cells as well as smooth muscle cells was confirmed by using anticytokeratin and antidesmin antibodies, respectively. The proliferative activity of the tumor cells was confirmed by using proliferating cell nuclear antigen immunostaining. The other cases of teratoma in wild and domestic birds are reviewed briefly.
