These are benign, vascular hamartomatous derivatives of the glomus body. A Glomus body is a normal intradermal arteriovenous anastomosis that arises from the neuromyoarterial glomus. They regulate skin temperature. They are present in the tips of the digits, particularly in the subungal areas. Histologic findings include endothelial pericytes and numerous nonmyelinated nerve fibers. Glomus tumors account for approximately 1% of all hand tumors and are even less common in children. Glomus tumors are more common in women between 30 and 50 years of age and generally occur spontaneously. Glomus tumors present as a classic triad of severe pain, point tenderness, and cold sensitivity.
