Abstract:
The Okinawa rail (Gallirallus okinawae) is an endangered species that inhabits the northern part of Okinawa Main Island in southern Japan. A wild Okinawa rail was rescued from a road in Kunigami Village in Okinawa in October 2009. The bird subsequently died and underwent necropsy. Tumors were found in the liver, spleen and part of the small intestine. Microscopically, lymphoid neoplasm was confirmed in these tissues. The tumor cells were mainly positive for CD3 and CD8α by immunohistochemistry. No Marek's disease virus genes were detected by PCR of a liver tumor. This is the first report of T-cell lymphoma in the Okinawa rail.
