Canine multiple cartilaginous exostoses: unusual manifestations and a review of the literature.
Multiple cartilaginous exostoses were diagnosed in a two-year-old Great Dane and a four-month-old border collie. Clinically, the Great Dane showed only mild discomfort, while the border collie exhibited tetraparesis due to cervicothoracic compression. Unusual features in the Great Dane were exostoses that bridged physes, with progression after skeletal maturity. The border collie puppy's exostoses resembled tumoral calcinosis radiographically. Limb exostoses in this puppy often were para-articular, and most were not attached to the underlying bone. These features resembled metachondromatosis in humans. Analysis of previously reported cases of multiple cartilaginous exostoses indicated that the prognosis is guarded to poor.
