RESUMO
A 2-month-old Pacific parrotlet (Forpus coelestis) was presented for assessment following a traumatic injury to the right wing that resulted in persistent swelling and inflammation. Six weeks postinjury the bird underwent surgical resection of a large hemorrhagic cavitated mass that had formed at the site of the original injury and a second, smaller mass on the body in direct contact with the wing mass. Histopathology of the wing mass confirmed a diagnosis of hemangiosarcoma. While commonly diagnosed in domestic species, hemangiosarcoma is uncommonly reported in avian species. To the authors' knowledge, this is the first report of hemangiosarcoma in a Pacific parrotlet and describes the development of hemangiosarcoma in a psittacine bird following trauma-induced inflammation.
