ROSA, Chantal  e  KIRBERGER, M. Kirberger. Extraskeletal osteochondroma on a cat's elbow. J. S. Afr. Vet. Assoc. [online]. 2012, vol.83, n.1, pp.79-83. ISSN 2224-9435.

A solitary extraskeletal osteochondroma was diagnosed in a 6-year-old, castrated male Burmese cat, positive for feline leukaemia virus (FeLV). The cat presented with a rapidly growing, solid, non-painful mass on the craniolateral aspect of the left elbow. Radiographs revealed an oval, well circumscribed 2.0 cm x 1.5 cm x 1.5 cm mineralised mass separated from the underlying bone. Surgical excisional biopsy confirmed the diagnosis. Feline extraskeletal osteochondromas are benign tumours frequently seen in FeLV-positive cats which can transform into osteosarcomas or chondrosarcomas. Radiographically, they cannot be distinguished from a parosteal or an extraskeletal osteosarcoma.
