We treated eleven cases of subungual exostosis. Three male and eight female patients aged 3 to 46 years (mean, 14.1 years) were included. All cases showed nail deformity and pain in the involved area at the first visit. Although eight of eleven cases (72.2%) had the exostosis on the great toe, one case with multiple exostosis showed subungual exostosis on the right index finger and left ring finger. All cases were treated by excision of the tumors. There was no local recurrence, however residual nail deformities were recognized in two cases. Although confirmed episode of significant trauma was seen only in one case, repeated minor trauma was considered the main cause of this disease. Local excision is the treatment of choice. It is essential that fibrocartilaginous cap must be completely excised to prevent recurrence.
