Subungual exostosis following toe nail removal--case report.

Removal of toe nail is a minor procedure that can be under ring block with no significant complications. We report the case of a young lady who developed a rapidly growing subungual exostosis on her right great toe following nail removal. Inadvertent iatrogenic injury to the nail bed and underlying phalangeal periosteum during nail removal might have triggered off rapid bone growth resulting in the large exostosis. To our knowledge, this aetiology for subungual exostosis formation has not been reported before.
