Glomus tumor (glomus cell tumor) is a rare, hamartomatous, usually benign neoplasm, whose cells resemble the modified smooth muscle cells of the normal glomus body. The diagnosis of a lower extremity is often delayed, due to the lack of awareness and low level of suspicion, by the treating physician. The glomus tumor (GT) often involves the nail beds. The unusual location of the lower extremity...

Glomus tumor is an uncommon benign tumor rising from the glomus bodies. It is most often found on limbs and rarely involve the head and neck. In this report, we present the 31st documented case of a intranasal glomus (nasal vestibular) tumor, an extremely rare localization.

Glomus tumors are usually benign tumors that occur in the skin and soft tissues of the extremities. Visceral locations, such as stomach, intestines or lung, are extremely rare because glomus bodies are rare or absent in these organs. This report describes our experience in a 47-year-old woman diagnosed with a peritoneal malignant glomus tumor. This finding has not been previously reported.

Li Y-L, Zheng H, Ding Y, Schultz HD. Expression of neuronal nitric oxide synthase in rabbit carotid body glomus cells regulates large-conductance Ca -activated potassium currents. J Neurophysiol 103: 3027–3033, 2010. First published March 31, 2010; doi:10.1152/jn.01138.2009. Our previous studies show that a decrease in endogenous nitric oxide (NO) is involved in the blunted outward K currents i...

Introduction. A glomus tumor is a benign vascular tumor derived from glomus cells and occurs mainly in the subcutaneous layer of the subungual or digital pulp. Extradigital glomus tumors have been reported within the palm, wrist, forearm, foot, bone, stomach, colon, cervix, and mesentery. Glomus tumors can originate from the intraosseous, intramuscular, periosteal, intravascular, and intraneura...

Glomus tumors arise from the glomus body, a neuro-arterial structure that regulates the body temperature. Most common site is the skin and superficial soft tissues of the distal extremities, especially the subungual region. Up to 10 % of patients may have multiple lesions. Rare anatomic sites include bone, particularly phalanges, stomach, mediastinum and lung. The head and neck region is a rare...

An extremely rare case of malignant glomus tumor originating in the superior mediastinum was evaluated immunohistochemically and ultrastructurally. A 78-year-old woman who had been suffering from dysphagia and dyspnea had poorly-defined soft tissue mass, 4.5 x 2.5cm, in the superior mediastinum with direct invasion into the esophagus, trachea, and bilateral thyroid glands. This case is believed...

A glomus tumor is an uncommon soft tissue tumor that is most commonly found in the subungual area and a glomus originating in the trachea is extremely rare. Histologically and ultrastructurally, these tumors have been divided into three subtypes: classic glomus tumors, glomangiomas, and glomangiomyomas. Glomangiomyomas account for less than 10% of all glomus tumors and are the least common type...

Glomus tumors are rare benign hamartomas arising from the neuromyoarterial glomus body, a highly specialized arteriovenous anastomosis responsible for thermoregulation. Although classically associated with a subungual location, less common extradigital glomus tumors can present a diagnostic challenge because of their rarity and nonspecific presentation. This case report adds to the literature o...

Surface temperature response to 15 agents was studied at 20 C. and 55 per cent humidity. Toe temperature was considered representative of the body's "glomus area." Temperatures at forehead and cheek represented the "blush area." Diethylaminoethanol, Hydergine, tetraethylammonium chloride, Priscoline, hexamethonium, Ilidar and Dibenzyline produced a prompt rise in temperature in the glomus area ...
