Abstract
Subungual exostosis is a relatively rare benign bone tumor occurring on the distal phalanx. We experienced eight cases (four male, four female) between 1978 and 1991. The mean age of patients at the time of diagnosis was 21 years (range, 10 to 51). No patients had any history of trauma. Histologically, four cases were diagnosed as osteochondroma-type, and three exostosis-type. No recurrences and nail deformities were noted.
