Abstract
Budgerigar is a common name for a colorful Australian native bird belonging to the Melopsittacus undulatus species. It is a very familiar pet around the world and its breeding has been grown in Iran. This study was conducted on a 2-year-old budgerigar with a nodular mass on the left wing. Physical examination revealed a firm, round and well-circumscribed mass approximately 1.70 cm in diameter. Radiographs showed a soft tissue mass with no involvement of bony structures. Fine needle aspiration was performed and the sample was cultured. In cultural examination, Klebsiella spp. were isolated in pure culture. Genus and species of the bacteria were confirmed using multiplex polymerase chain reaction. The mass was surgically excised and it was mainly composed of numerous, large lipid-laden macrophages containing abundant vacuolated cytoplasm, extracellular acicular cholesterol clefts and large number of multinucleated giant cells (especially multinucleated Touton giant cells) in the dermis. Finally, a diagnosis of cutaneous xanthogranuloma was made based on histopathological findings.
