What is the most common benign skeletal neoplasm?
Osteochondroma is the most common benign skeletal neoplasm. This lesion accounts for 20% to 50% of benign bone tumors and 10% to 15% of all bone tumors. Osteochondromas occur most commonly in the first two decades of life, arise from the metaphysis pointing away from the joint, and can be either flattened (sessile) or stalklike.
There is usually cessation of growth of the osteochondroma after closure of the growth plate. Osteochondromas can occur after radiation therapy in children and may present with pain because of mechanical irritation or fracture.
