[Glomus tumor of the nail area. Apropos of a series of 55 patients].
OBJECTIVE
Glomus tumors are infrequent in the hand. We have review 55 cases, localized in the nail area to discuss their diagnosis and surgical approach.


METHODS
Out of 80 glomus tumors of the hand seen in two hand units, 55 were located around the nail area, 33 in the nail bed area, 8 at the nail root and 14 laterally. The population was predominantly female (42 cases) and the mean age 43 years. The mean delay before presentation was 37 months. Pain was the main symptom (97 per cent) increased by trauma and cold. A blue spot was visible in 15 cases and diagnosis was performed on clinical ground in all cases except two. A notch was present on X-ray in 16 cases. A prospective study with MRI allow a diagnosis in 18 of 21 cases. All tumors were removed through a lateral approach elevating the nail complex and confirmed histologically.


RESULTS
The diagnosis was per-operatively confirmed in 53 cases and performed in one case. The last case of supposed hemangioma was modified at histological examination. No case of nail dystrophy (not existing pre-operatively) or residual pain was seen at the 81 months of follow up. Seven recurrences were observed, 4 of them having been operated initially in our units.


CONCLUSIONS
Clinical diagnosis could be performed on clinical grounds. MRI is to be reserved to recurrences or multi-operated patients. Risk of recurrence has to be mentioned pre-operatively to the patient.


CONCLUSIONS
Lateral approach with nail complex elevation is safe, allowing excision of the tumor without nail dystrophy.
