Interpretive Summary: This study documents the occurrence of a rare tumor involving cells associated with blood vessels in a Golden pheasant. There was no evidence in this animal of any virus type known to cause tumors in chickens or other avian species.

Technical Abstract: A 13-year-old male Golden pheasant (Chrysolophus pictus) was examined for a hemorrhagic mass on the leading edge of the right propytagial area of one day's duration. Physical examination revealed a scabbed mass that bled easily when manipulated. Two biopsies revealed acute hemorrhage and cellulitis. The mass was removed under general anesthesia and histopathology demonstrated a hemangiosarcoma. Assays on white blood cells for avian leukosis/sarcoma viruses, Marek's disease viral serotypes 1, 2, and 3, and reticuloendotheliosis virus were negative. The bird recovered uneventfully, but the tumor recurred within 10 days of removal. Upon clinical deterioration three months later, the bird was euthanized. .
