Polyostotic Chondroblastic Osteosarcoma in a Kestrel (Falco tinnunculus)

Abstract We report a case of polyostotic chondroblastic osteosarcoma in a kestrel (Falco tinnunculus) admitted to the Wildlife Rehabilitation and Rescue Center (Naples, Italy). A consolidated fracture of the left tibiotarsus bone and a deviation of the limb were evident. After radiographic, cytologic, and histopathologic examinations, a diagnosis of polyostotic chondroblastic osteosarcoma was made. To our knowledge, this is the first report on polyostotic chondroblastic osteosarcoma in a kestrel.
