Hereditary multiple exostoses is a relatively uncommon disorder of endochondral bone characterized by the presence of multiple, cartilaginous-capped exostoses arising from the metaphyses. A rare presentation of hereditary multiple exostoses in the calcaneus of a 35-year-old man is reviewed and discussed. A brief review of the literature is provided, as well as a discussion of the patient's family history.
