Plain-English summary
A 3-year-old Appaloosa stallion had a noticeable growth on his nasal bone that measured about 4 cm by 4 cm by 2.5 cm. X-rays showed that the mass was made of bone, with a solid outer edge and some lighter areas inside. The growth was surgically removed and examined under a microscope, which confirmed it was an osteochondroma, a type of bone tumor. This is the first time such a tumor has been reported in a horse's nasal bone. The treatment was successful in removing the mass.
Abstract
A 3-year-old Appaloosa stallion with a 4 cm x 4 cm x 2.5 cm mass protruding from his nasal bone was evaluated. Radiographs revealed an osseous mass, with a radiopaque outer margin and several radiolucent areas within the body of the mass. The mass was surgically removed and evaluated histopathologically. The histopathological diagnosis was osteochondroma. This case represent the first reported occurrence of an osteochondroma arising from intramembraneous bone in the horse.
