Extra-Adrenal Paraganglioma (C0030422)

Definition (MSH) A relatively rare, usually benign neoplasm originating in the chemoreceptor tissue of the CAROTID BODY; GLOMUS JUGULARE; GLOMUS TYMPANICUM; AORTIC BODIES; and the female genital tract. It consists histologically of rounded or ovoid hyperchromatic cells that tend to be grouped in an alveolus-like pattern within a scant to moderate amount of fibrous stroma and a few large thin-walled vascular channels. (From Stedman, 27th ed)
Definition (NCI) A benign or malignant paraganglioma arising from sympathetic or parasympathetic paraganglia outside the adrenal gland.

Glomus Tumor (C0017653)

Definition (MSH) A blue-red, extremely painful vascular neoplasm 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. It is composed of specialized pericytes (sometimes termed glomus cells), usually in single encapsulated nodular masses which may be several millimeters in diameter (From Stedman, 27th ed). CHEMODECTOMA, a tumor of NEURAL CREST origin, is also sometimes called a glomus tumor.
Definition (NCI) A rare benign or malignant mesenchymal neoplasm arising from cells that resemble the modified smooth muscle cells of the glomus body. The majority of glomus tumors occur in the distal extremities.
