Minimally Invasive Transungual Tumors Enucleation With Nail Preservation for Subungual Glomus Tumors

BACKGROUNDGlomus tumors are benign neurovascular neoplasms, most commonly located in the subungual region. These subcutaneous nodules are characterized by intense pain and temperature sensitivity. Although surgical excision is the curative treatment, permanent nail deformity and recurrence are not uncommon after conventional surgery.OBJECTIVEThis study evaluated the long-term efficacy of a modified transungual approach with nail preservation for removing subungual glomus tumors.MATERIAL AND METHODSThirty-nine patients with clinically diagnosed and histopathologically proven glomus tumors treated at a medical center over a 13-year period (2007-2019) were retrospectively evaluated.RESULTSThe 39 patients included 28 women and 11 men (ratio, 2.5:1), with a mean age of 48.9 years. Thirty-four tumors were located in the fingers and 5 in the toes. All patients returned to normal activity soon after the surgery. At a mean follow-up of 28.8 months, all were pain free or experienced minimal pain and were satisfied with treatment outcomes. One patient (2.6%) experienced recurrence. No nail deformity was observed.CONCLUSIONThe transungual approach with nail plate preservation is a novel and effective method for removing subungual glomus tumors with reduced postoperative pain and rapid healing, while preserving or improving the configuration of the nail.
