However, it rarely occurs subungually. In this location, the lesion may penetrate the skin, causing nail deformity, and can easily be misdiagnosed. We report two cases of subungual osteochondroma of the distal phalanges of the first toes with cutaneous penetration and discuss the clinical, histologic, and radiographic features and the treatment options.
