A 27-year-old female African grey parrot (Psittacus erithacus) presented as a referral for surgical removal of an enlarged uropygial gland that was first observed by the owner 6 months prior. Antibiotic therapy was attempted by the referring veterinarian with limited treatment response. No abnormalities were noted in the results of a complete blood count and plasma biochemistry panel. Computed tomographic imaging of the parrot showed a left-sided uropygial gland mass with no evidence of metastasis or invasion into the underlying soft tissue or bone. The uropygial gland was surgically excised in an attempt to obtain clean margins devoid of tumor cells. Histopathological evaluation of the submitted tissue was suggestive of an intraluminal uropygial gland epithelioma. Intraluminal epithelioma should be considered as a differential diagnosis in psittacine species that are presented with an asymmetrically enlarged uropygial gland.
