The differential diagnosis should include hereditary multiple osteochondromas (MO; see this term) in which the long bones are predominantly affected and the lesions point away from the joint/growth plate and may result in shortening or deformity of the affected bones. Other diseases to be considered include the non-hereditary conditions Ollier disease and Maffucci syndrome (in which multiple enchondromas are found in the medulla of the bone and are predominantly unilateral), and dysplasia epiphysealis hemimelica (DEH; characterized by a cartilaginous overgrowth mainly located in the lower extremities on one side of the body) (see these terms).

My daughter, 5 yrs old, has three lumps on her right shin that have not gone away. I am starting to look up what this might be and am scheduled for an ultrasound and x-ray for her soon. I was researching metachondromatosis - is this something that when felt is attached to the bone itself, is it bone, or is it a lump that can be moved around? See answer
