In the foot, osteochondromas develop under the toenail. They are benign (non-cancerous) bone tumors that form as a result of trauma to the toe, usually in children and young adults. Osteochondromas are typically asymptomatic, causing no pain or visible change to the toe. However, as they progress, they may alter the shape of the toenail, resulting in ingrown toenails, or affect the bone surface in a way that affects normal function. Osteochondromas can be surgically removed, but are known to recur in certain individuals.
