What Is Hereditary Multiple Exostoses?

Q:
What is hereditary multiple exostoses?

A:
Hereditary multiple exostoses (HME) is a rare genetic condition in which there are multiple exostoses (bone tumors). Another name for it is hereditary multiple osteochondromas (HMO).

Usually, these bone tumors are on the growing end of the long bones of the legs and arms. They affect bone growth.

Therefore, the symptoms of HME include abnormal bone growth, and lumps in some cases.

Since these bone tumors are benign (non-cancerous), mostly there is no need for treatment. But, when it’s unfortunately serious, a surgical correction may be necessary.
