Multiple Hereditary Osteochondromatosis - case report and review of literature

Multiple hereditary osteochondromatosis (MHO) is an autosomal-dominant skeletal dysplasia affecting bones formed by enchondral ossification. The disorder is alternately referred to as multiple hereditary exostoses, multiple cartilaginous exostoses, multiple osteochondromata, diaphysealaclasis, osteogenic disease, and dyschondroplasia. Clinical evidence of the disorder (exostoses) occurs in the first decade of life. The characteristic osteochondromas are usually located on the metaphysis of long bones. Here we report a twelve year old boy with multiple hereditary osteochondromatosis.
