Subungual osteochondroma, a rare disorder of the fingers and toes, occurred in five patients. Clinical features of the condition include nail deformation, history of long, slow growth, and characteristic radiologic features. Surgery is directed toward total tumor resection with preservation of the nailbed to achieve normal nail growth. Differential diagnosis included bony, cartilaginous, and soft tissue tumors as well as cystic lesions. Malignant tumor should be suspected but not confused with this benign disorder. Roentgenologic examination is indicated in the differential clinical diagnosis of any subungual mass.
