Severe Multiple Cartilaginous Exostoses

Multiple cartilaginous exostoses (MCE) is one of the most common inherited skeletal disorders. A collection of 1124 cases was reported by Stock and Barrington (1925). Recently other large series have been published by Solomon (1963) and Sauer (1979). Different terms have been used for it such as multiple exostoses, hereditary multiple exostoses and diaphyseal aclasis. The swelling or "lump" are reported commonly to be located at the end of the long bones, in the scapula, pelvis, ribs, and rarely in the spine and skull. Growth disturbance of the bone is generally recognized but rarely results in true dwarfism. Commonly, there is little disturbance in health or activities in daily life.
