BACKGROUND Glomus tumors are rare mesenchymal tumors originating from glomus bodies in the skin. Glomus tumors of the kidney are rare tumors and only a few cases have been reported in the medical literature. An extensive search revealed a very limited number of primary renal glomus tumors. Although most of these cases were benign in nature, including a case with uncertain diagnosis of malignant...

Glomus tumors are rare neoplasms that typically occur within the dermis or subcutis of the subungual space. Primary glomus tumors of the thorax are exceedingly uncommon, thus standard-of-care management is lacking. In this report we describe the management of a patient presenting with a symptomatic glomus tumor of the posterior trachea, and provide a comprehensive review including all documente...

Glomus tumors are uncommon, benign, small neurovascular neoplasms derived from glomus bodies in the reticular dermis. Glomus bodies are found throughout the body to regulate body temperature and skin circulation; however, they are concentrated in the fingers and the sole of the foot. The typical presentation is a solitary nodule in the subungual or periungual area of the distal phalanx. The pri...

Glomus tumors are unusual and generally benign neoplasms mainly found in subungeal areas. We describe a case of concomitant subcutaneous and tracheal glomus tumor that underwent successful endoscopic resection. A 48-year old male with a left forearm subcutaneous mass presented with hemoptysis. A chest CT scan demonstrated a polypoid tracheal lesion. He underwent a bronchoscopic resection. A bio...

Our previous studies show that a decrease in endogenous nitric oxide (NO) is involved in the blunted outward K(+) currents in carotid body (CB) glomus cells from chronic heart failure (CHF) rabbits. In the present study, we measured the effects of the neuronal nitric oxide synthase (nNOS) transgene on the K(+) currents in CB glomus cells from pacing-induced CHF rabbits. Using single-cell real-t...

BACKGROUND Glomus tumors have recently been reported in individuals with the neurofibromatosis type 1 (NF1) cancer disposition syndrome. We compare the clinical and molecular features of these painful hamartomas in a series of sporadic and NF1-associated cases. OBJECTIVE We sought to evaluate the association of NF1 with glomus tumors and to compare NF1-associated glomus tumors with sporadic g...

BACKGROUND Glomus tumor is an uncommon neoplasm derived from cells of the neuromyoarterial glomus or glomus body. Most glomus tumours occur in the dermis and subcutaneous tissues. A case of a primary pulmonary glomus tumour originating in the right upper lobe is presented. CASE PRESENTATION A 74-yr-old male was admitted with siccus cough, dyspnea and right-sided chest pain. Computed tomograph...

Roy, Arijit, Jinqing Li, Abu-Bakr Al-Mehdi, Anil Mokashi, and Sukhamay Lahiri. Effect of acute hypoxia on glomus cell Em and m as measured by fluorescence imaging. J Appl Physiol 93: 1987–1998, 2002. First published August 2, 2002; 10.1152/japplphysiol.00725.2001.—We have reinvestigated the hypothesis of the relative importance of glomus cell plasma and mitochondrial membrane potentials (Em and...

Glomangiomas (glomus tumours) are uncommon, and in most cases are benign perivascular tumours, usually located in the dermis of the extremities, especially in the subungual region of the fingers. They also occur in other organs and in other regions of the body. Histogenetically, they are derived from modified smooth muscle cells of the glomus apparatus, which is associated with temperature regu...
