A simple and efficient surgical technique for subungual exostosis.

Subungual exostosis is a benign osteochondral tumor usually involving the distal phalanx of the great toe. The lesion most frequently occurs in the second and third decades of life and is rare before the age of 10 years. There are few reports of its occurrence in children, and most of them advocate partial or complete nail excision to treat this lesion successfully. We report our experience with six children and adolescents using a simple surgical technique that involves approaching the exostosis under the nail to preserve nail coverage. Rapid recovery and excellent cosmetic appearance were achieved immediately after the operation.
