Abstract

Lymphoid neoplasia is the most common form of hemolymphatic neoplasia in birds. Most research on avian lymphoid neoplasia has been done on the virus-induced neoplasias affecting poultry, including Marek's disease, avian leukosis, and reticuloendotheliosis. There is evidence of virus-induced lymphoid neoplasia in psittacine and passerine species, but little research has been done to confirm it. We diagnosed multicentric lymphoma on histopathologic examination of tissues from a European starling (Sturnus vulgaris) that had presented because of inability to fly, dyspnea, emaciation, and abdominal distension. Macroscopic and histologic findings were similar to those for lymphoid leukosis as described in chickens. Polymerase chain reaction amplification using chicken reticuloendotheliosis virus primers was negative. Amplification of a pol fragment from primers by polymerase chain reaction showed the presence of retrovirus sequences in the starling tumor.
