En Bloc Excision and Bone Grafting for Monostotic Multiple Intraosseous Glomus Tumors of the Distal Phalanx

Abstract

Case: Glomus tumors of the hand are rare tumors that occur predominantly in the subungual region. Though multicentric glomus tumors have been reported in the subungual region involving the nailbed, monostotic multiple intraosseous glomus tumors have not been reported so far. We report a case of a 36 year-old woman who presented with a 5-year history of intermittent thumb pain, aggravated with exposure to cold or pressure. A glomus tumor of the thumb was excised, but symptoms returned 3 months later. She ultimately underwent curettage with bone grafting of a recurrent glomus tumor at the same site, and has been free of symptoms for 1.5 years. Conclusion: Intraosseous glomus tumors may present as multiple synchronous lesions. This, to the best of our knowledge, is the first case report of monostotic multiple intraosseous glomus tumors.
