Hereditary Multiple Exostoses

Hereditary Multiple Exostoses (HME) is a medical condition whereby multiple exostoses (bony spurs or lumps, also known as osteochondromas) develop on the bones of a child. Generally, when a person with HME reaches maturity, and their bones stop growing, the exostoses also stop growing.

It is estimated to occur in 1 person in 50,000. A person with HME is more likely to develop a form of bone cancer called chrondosarcoma as an adult.

It is an autosomal dominant disorder.

If necessary, the exostoses can be removed by surgery.
