Osteochondroma is the most common benign bone tumor1, and it usually occurs between the ages of ten and fifteen years1. Osteochondromas usually increase in size throughout childhood and then stop growing at skeletal maturity2. If there is growth or a change on the radiographs of an osteochondroma in an adult, malignant transformation to a chondrosarcoma is usually suspected3. We report the case of an adult with a solitary osteochondroma of the humerus that continued to grow to a very large size but did not show malignant changes on histological examination after excision. The patient was informed that data concerning the case would be submitted for publication, and he consented.
