Multiple glomus tumor: a case report and review of the literature

Multiple glomus tumors are extremely rare and differ from the more common solitary glomus tumors in their clinical presentation and histological features. The authors report a case of multiple glomus tumors of the right hand in a 65-year-old man, its treatment, and a review of the features of this uncommon tumor. The tumor usually presents as a painful, firm, purplish, solitary nodule of the extremities, especially in the nail bed. Multiple glomus tumors are described as softer, more compressible, bluish nodules and they occur with less frequency than solitary tumors. They are often inherited in an autosomal dominant pattern. The authors present a case of multiple glomus tumors of the right hand, in which many small, painful, red papules were grouped in the right hypothenar region. The patient was treated by wide excision of the lesion and coverage of the defect with an ulnar artery forearm flap.
