In 1924 Barré and Masson described a peculiar neoplasmatic process occurring generally at the fingertips, specifically in the nail bed, and more infrequently elsewhere, such as at the wrist, the ears, and the nose. Because of this eclectic localization under the nails, the dermatologists named this lesion "subungual tumor of the glomus." Histologically, however, it is regarded as an angioneuromyoma and is referred to in the literature as "glomus tumor" or "cutaneous glomus tumor" or "glomangioma." The term "glomus tumor" may cause confusion with paragangliomata which many authors also name glomus tumors. In the literature the paraganglion is very frequently called glomus (because of the abundant blood vessels that constitute its substrate), and the neoplasms of the paraganglia, glomus tumors. These however have nothing to do with cutaneous glomus tumors or glomangiomata developing in the fingertips. The similarity of these two neo formations is only morphological and not histogenetic.
