A calcaneal osteochondroma with recurrence in a skeletally mature patient: a case report

Introduction Osteochondroma is the most common benign tumor of the skeleton. However, calcaneal osteochondroma is very rare. Osteochondromas grow during childhood through adolescence, but usually growing ends when the epiphyseal plates close. In an adult, growth of an osteochondroma suggests the diagnosis of malignant transformation to a chondrosarcoma. However, enlargement of an osteochondroma reported as benign after skeletal maturity is present in literature.
