Subungual glomus tumors. Value of the direct dorsal approach.

The authors operated upon 4 subungual tumors between november 1975 and july 1976. In three cases, the tumor was located under the center of the nail and a direct dorsal approach--atraumatic detachment of the nail and approach via a longitudinal incision of the nail bed--was employed. Excision was performed using microsurgical technique. After trimming and perforation (classical techniques), the nail was replaced and fixed. This approach clearly identifies the boundaries of the tumor and facilitates radical removal. The cosmetic result is excellent. No recurrences have been seen with a 5 year follow-up.
