Abstract
Subungal exostosis is a rare benign cartilaginous tumor affecting the distal phalanx. From 1995 to 1996, six subungal exostoses of the hallux were treated in the Chonnam national university hospital. The symptoms were subungal pain, mass on the distal phalanx elevating the nail or causing ulceration of the nail bed. The plain radiological examination showed a bony mass occurring on the dorsomedial or medial aspect of the distal phalanx. The diagnosis of the subungal exostosis of the hallux were suspected from clinical presentation and confirmed with radiographic examination. Histological patterns were fibrocartilaginous cap with the mature trabecular bone. Complete excision of the lesion including overlying nail bed was curative without recurrence in all cases.
