Femoral osteochondroma presenting with rupture of vastus medialis muscle

Abstract

Osteochondroma is one of the most common benign tumors of the skeletal system, which is usually seen in adolescence. It is responsible for about half of all healthy bone tumors and 15% of bone tumors. Osteochondral lesions are often seen in the metaphyseal region of the long bones and frequently occurred in the proximal humerus, distal femur, and tibia. Malignant transformation is the most serious complication in 1%, and about 5 to 25% of solitary and multiple form the cases, respectively.[1]
