ABSTRACT
Osteoma is an uncommon bone formation documented in avian species and other animals. A blue-fronted Amazon parrot (Amazona aestiva) with clinical respiratory symptoms was examined because of a hard mass present on the left nostril. Radiographs suggested a bone tumor, and the mass was surgically excised. Histopathologic examination revealed features of an osteoma. To our knowledge, this is the first description of an osteoma in a blue-fronted Amazon parrot. Osteoma should be considered as a differential diagnosis in birds with respiratory distress and swelling of the nostril.

As neoplasias do sistema tegumentar são relativamente comuns em aves de cativeiro. Os tumores localizados na derme, emaves de estimação, podem ser de origem epitelial e mesenquimal, sendo que os carcinomas de células basais parecem serextremamente raros em aves. Um periquito macho adulto foi encaminhado a uma clínica particular apresentando uma massatumoral na epiderme, e localizada na região medial do úmero direito. Optou-se pela amputação da asa afetada e o diagnósticode carcinoma de células basais foi feito pela histopatologia.
Tumors of the integumentary system are relatively common in captive birds. Dermal tumors in pet birds can be epithelial andmesenchymal in origin. Basal cells carcinomas appear seem to be extremely rare in birds. An adult male budgerigar wasexamined exhibiting a tumor mass situated at the epidermis and in the medial region of the right humerus. The wing wasamputated and histopathology diagnosis identified basal cell carcinoma.
