Abstract
Osteochondroma is a benign cartilaginous outgrowing neoplasm arising from the surface of the long bone consisting of cartilage-capped bony overgrowth with extension of native bone marrow. It is the most common primary bone tumor. It is approximately 1.5 times more common in male than female. About half the cases occur in the second decade of life. There is predilection for the distal femur, followed by the proximal humerus and proximal tibia. Roentgenograms show a pedunculated or sessile protuberance from the long bone metaphysis. The cortex of the host bone flares out into the osteochondroma cortex. The cartilage cap is covered by a thin periosteal membrane. The limit between the cartilage cap and the underlying cancellous bone shows endochondral ossification, closely mimicking a normal epiphyseal plate. Treatment is surgical excision with the entire cartilage cap.
