Glomus tumors are rare mesenchymal neoplastic lesions arising from glomus bodies that are involved in skin thermoregulation. They are mostly benign tumors, and malignant variants have been rarely reported. The subungual zones of fingers and toes are the most frequent sites of observation. Glomus tumors arising in visceral organs of the gastrointestinal tract are exceedingly rare. Stomach antrum...

Glomus tumour are painful swelling arising from glomus bodies. They are very rare in occurrence. Most of the time the presenting symptoms is severely painful fingertip without palpable swelling. Their most common location is the subungual region of digits. We report the rare case of a glomus tumour located in an uncommon location, i.e., at the tip of right thumb medial aspect near to tendon att...

Fig 1. A glomus tumor of the hypothenar eminence. Photo from clinical examination shows a hyperkeratotic papule. Note the resemblance of a foreign body. INTRODUCTION Glomus tumors are rare, benign vascular neoplasms typically localized to the digits, with a propensity for the subungual region of the hand. These subcutaneous hamartomas are derived from hyperplasic modified smooth muscle cells, s...

Glomus tumors were described by Rosenwasser in 1945 (1). Glomus body tumors, often abbreviated as glomus tumors, are also known as paragangliomas or chemodectomas. They are a family of benign hypervascular neoplasms arising from the chief cells of the paraganglionic tissues. Furthermore, glomus tumors have vascular structure, comprising cell bundles stained with non chromaffin among thin-walled...

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...
