Glomus Tumor

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. [from MeSH]

Paragangliomas 1

Hereditary paraganglioma-pheochromocytoma (PGL/PCC) syndromes are characterized by paragangliomas (tumors that arise from neuroendocrine tissues symmetrically distributed along the paravertebral axis from the base of the skull to the pelvis) and by pheochromocytomas (paragangliomas that are confined to the adrenal medulla). Sympathetic paragangliomas hypersecrete catecholamines; parasympathetic paragangliomas are most often nonsecretory. Extra-adrenal parasympathetic paragangliomas are located predominantly in the skull base, neck, and upper medistinum; approximately 95% of such tumors are nonsecretory. In contrast, sympathetic extra-adrenal paragangliomas are generally confined to the lower mediastinum, abdomen, and pelvis, and are typically secretory. Pheochromocytomas, which arise from the adrenal medulla, typically hypersecrete catecholamines. Symptoms of PGL/PCC result either from mass effects or catecholamine hypersecretion (e.g., sustained or paroxysmal elevations in blood pressure, headache, episodic profuse sweating, forceful palpitations, pallor, and apprehension or anxiety). The risk for malignant transformation is greater for extra-adrenal sympathetic paragangliomas than for pheochromocytomas or skull base and neck paragangliomas. [from GeneReviews]

Glomangiomyoma

A morphologic variant of the glomus tumor with architectural features similar to solid glomus tumor. It is characterized by the presence of elongated glomus cells which resemble mature smooth muscle. [from NCI]

Glomangioma

A morphologic variant of the glomus tumor characterized by the presence of dilated veins, surrounded by small clusters of glomus cells. Glomangiomas are most often present in patients with multiple lesions. [from NCI]
