Treatment of subungual glomus tumour.

We reviewed 30 patients with subungual glomus tumours of the hand operated on between 1964 and 1997. Seven patients were male and 23 were female. Their age ranged from 16 to 78 years. A transungual approach was selected in 27 patients, and a periungual approach in three. Pre-operative pain subsided in all of the patients, but recurrence of the pain was observed in nine. Nail deformities were observed in nine patients before surgery. After surgery, it disappeared in three patients, persisted in six, and new deformities developed in five. To avoid recurrence of pain, it is important that the accurate pre-operative localisation of the tumour and a complete extirpation should be performed. To avoid nail deformity, it is better to apply a periungual approach for tumours developing in the peripheral region, and a transungual approach followed by meticulous repair of the nail bed for tumours developing in the central region.
