Glomus tumour: a rare differential for subungual lesions.

A 21-year-old, usually fit and well man, presented with a 10-year history of intermittent, paroxysmal pain and temperature sensitivity to his right thumb. He felt this was associated with a subungual lesion present on the same digit. He was diagnosed as having a glomus tumour and was referred to the hand surgeons for surgical excision.
