Abstract:
A 10-year-old, female umbrella cockatoo (Cacatua alba) was presented for evaluation of a mass at the right commissure of the beak, with associated right periorbital swelling. A feather cyst was suspected, based on history and the results of a computed tomography scan and fine-needle aspirate. The cyst was surgically debrided and removed. Histopathologic results confirmed an infraorbital keratin cyst, most likely originating from a feather follicle. To our knowledge, this is the first reported case of a periorbital keratin cyst in a bird.
