Objectives/Interrogation: Subungual exostosis (SE) is a benign bone tumor found on the distal phalanx of a digit, beneath or adjacent to the nail. Dupuytren gave the first description of the lesion (published after his dead in 1847) when he reviewed his experience with 30 patients suffering from subungual exostoses of the great toe [1]. Nearly 80 percent of reported cases involve the great toe and the remaining cases involve other toes. Involvement of the finger by this lesion occurs very rarely, with less than 60 reported cases in the English language literature - most of them in the thumb.
We report 3 cases of sublingual exostosis in the fingers of female patients.
Methods: The patients underwent excision of the mass in the operating room in lokal anesthesia and finger block. After a short distal palmar incision the tumor was resected completely at the level of the normal periosteum. The distal border of the tumor was covers with cartilage.
Results and Conclusions: Finger SE are about 1.5 times more common in women than men. Unlike exostoses elsewhere in the body, SE often appear and continue to grow after skeletal maturity. About 50% present during the second or third decade of life, with the other half presenting in patients over age forty. Very often these lesions are misdiagnosed, leading to protracted morbidity from inadequate therapy or extreme treatments such as digital amputation or radiation therapy. We report three rare case of subungual exostosis on the fingers presenting as stony hard painful swellings in three female patients with complete and long time release of symptoms after surgery.
