Plain-English summary

A blue-fronted Amazon parrot was brought to the vet because it had trouble breathing and a hard lump on its left nostril. X-rays showed that the lump was likely a bone tumor, so the vet performed surgery to remove it. After examining the mass, the vet confirmed it was an osteoma, which is a rare type of bone growth. This case is significant because it's the first time an osteoma has been reported in this type of parrot. The parrot's breathing problems were likely related to the mass, and removing it should help improve its condition.

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.
