Cranial teratomas in two domestic ducks (Anas platyrhynchos domesticus).
Teratomas are rare tumors in domestic fowl, and none have been reported in the cranial area of ducks. Clinical signs and gross and microscopic findings associated with a cranial teratoma in two domestic ducks are reported. One tumor arose within the cranial vault and was associated with neurologic signs. The other tumor was subcutaneous and invaded the parietal bone but did not extend into the brain. Both tumors were tridermic.
