Definition

A blue-red, extremely painful paraganglioma involving a glomeriform arteriovenous anastomosis (glomus body), which may be found anywhere in the skin, most often in the distal portion of the fingers and toes, especially beneath the nail; They may also occur in the stomach and nasal cavity; It is composed of specialized pericytes (sometimes termed glomus cells), usually in single encapsulated nodular masses which may be several millimeters in diameter; When located in the usual subungual site, the abundant innervation makes the tumor exquisitely painful; when located elsewhere, the glomus tumor is painless----(From Dorland, 27th ed; Stedman, 25th ed; Segen, Dictionary of Modern Medicine, 1992)-------------
