Osteoma in Agapornis roseicollis

Abstract

Neoplasias are important causes of illness and death in domestic animals. However, in birds, they are less frequent compared with other species such as dogs and cats. Moreover, benign tumors of bone are even less frequent in captive birds being considered sporadic, which make it a poorly understood entity due to the lack of clinical and histopathological data. Thus, we present a case of an osteoma in a Peach-faced lovebird (Agapornis roseicollis) approaching clinical and morphological aspects. A two-years-old lovebird was referred to the veterinary hospital with a 4-month evolution round to oval tumoral mass on the wing. The nodule was firm, painful when manipulated. Radiographic examination revealed a radiopaque mass in the radius and ulna bones. The animal has died during the surgical procedures. The affected wing was submitted to pathology service and histopathology revealed an osteoma.
