Glomus tumor of the digits.

Eight cases of glomus tumor of the digits seen during an 8-year period are reviewed. This number comprised 1.2% of all hand tumors encountered. Symptoms of cold intolerance and exquisite tenderness were common to all. The average duration of symptoms prior to diagnosis and treatment was 7 years. Five patients gave a history of either frostbite (two) or trauma (three) prior to onset of symptoms. The tumor was subungual in six of the eight patients, with a relatively even distribution among all digits. Roentgenographic changes of erosion of the distal phalanx were present in 50% of the tumors. Surgical excision was curative in all instances.
