Abstract
- Subungual exostosis is an uncommon benign tumor of cartilaginous bone arsing adjacent to the distal phalanx of a digit. It is usually a solitary lesion that develops most often in substance of the great toe and less frequently in other toes. The rare presentation of subungual exostosis in a finger usually stimulates an extensive differential diagnosis. We present a case of subungual exostosis of the finger in a 54-year-old female. Roentgenographic findings showed stick-like calcified density on the tip of the distal phalanx of the left 5th finger. Histopathologic findings showed enchondral bone structure and surroundung cartilaginous tissues in the dermis. At 6-month follow-up, the result was excellent, with no sign of recurrence.
