Hereditary Multiple Exostoses
Book AppointmentHereditary multiple exostoses (HME), now known as hereditary multiple osteochondromas (HMO), is a genetic disorder which promotes the growth of multiple benign (noncancerous) osteochondromas (bone tumours). The tumours can appear at the end of long bones and on flat bones such the hip and the shoulder blade.
Osteochondromas (bone tumours) are made of cartilage and bone, and develop as a mass that grows away from the bone. Your child may inherit the gene from you but the tumours are not present at birth. Individuals affected by this disorder usually develop multiple exostoses by the age of 12. Once the child has reached their maximum height, the tumour stops growing and new tumours may also cease to develop.
It is an extremely rare disorder, occurring in 1 in every 50,000 individuals worldwide.
