What is multiple hereditary exostoses?

Also known as: hereditary multiple exostoses, hereditary multiple osteochondromas, diaphyseal aclasis.

Multiple hereditary exostoses is a genetic condition in which an individual develops multiple bone tumors on the ends of the bones, often at the ends of long bones or on the hips or shoulder blades. These tumors are non-cancerous but can cause growth problems for the affected bones. The condition is frequently referred to as multiple hereditary osteochondromas, as well.
