Subungual glomus tumours of the hand: diagnosis and outcome of the transungual approach

We report 17 patients with a subungual glomus tumour. All complained of pain and tenderness when touched, and nine patients experienced severe pain in the cold. A transungual approach with nail plate avulsion on one side was used in all cases. A surgical microscope was used to localise and dissect the tumour and to repair the nail bed and matrix. This method has produced good results, without local recurrence or postoperative nail plate deformity.
