CR – Multiple osteochondromas involving the humeri, scapulae and ribs.

Reveal Discussion

Multiple exostosis syndrome (MES) is a polynomic entity and may be referred to as multiple hereditary osteochondromatosis, osteochondromatosis, diaphyseal aclasis, external chondromatosis among others. MES is an autosomal dominant disorder. Osteochondromas may appear in any portion of the skeleton but tend to be more numerous and larger near the fastest growing joints (wrists and knees); osteochondromas of the carpal bones, sesamoid bones, vertebrae and skull are rare. Fifty percent of patients with multiple exostosis syndrome have lesions in the ribs. Complications include fractures, pneumothorax, vascular or neural compression, and malignant transformation to chondrosarcoma.
