Subungual glomus tumours: a different approach to diagnosis and treatment.

Nine cases of subungual glomus tumour in which a transillumination test was used for diagnosis and a different operative technique was used to prevent postoperative nail deformity are described. The transillumination test is a new method for identifying a glomus tumour. With our surgical technique it is simple to approach a glomus tumour under the proximal nail bed and it produces a minimal defect.
