Since STILLING proposed in 1892 that the carotid body contains cells which become brown after treatment in potassium dichromate, the chromaffinity of the carotid body has long been a matter of dispute (for a detailed discussion, see ADAMS 1958). The occurrence of catecholamines in every glomus cell has recently been identified by pharmacological and fluorescence methods (RAHN 1961, NIEMI and OJ...

Onychomatricoma and glomus tumor are two rare subungual neoplasms with distinct clinical and histopathological features. We report a case of onychomatricoma associated with a glomus tumor in the subungual region of the same finger in a 45-year-old woman. Histopathological examination revealed characteristic findings of both onychomatricoma and glomus tumor. To the best of our knowledge, these t...

Glomus tumor is a benign soft tissue neoplasm which commonly affects the subungual region of the fingers. But the tumors can also arise in the other sites such as the antrum of the stomach. We are reporting a case of a glomus tumor of the stomach in a 71-year-old female patient who presented with dyspepsia. The tumor was confined to the lamina muscularis propria, it consisted of round cells wit...

The response of pea (Pisum sativum cv. Avola) to arbuscular micorrizal fungi (AM) species Glomus mosseae and Glomus intraradices and Rhizobium leguminosarum bv. Viciae, strain D293 regarding growth, nodulation and nitrogen fixing activity was studied. Pea plants (Pisum sativum cv. Avola) were grown in a glasshouse until flowering stage (35 days) in 4 kg plastic pots using leached cinnamonic for...

We present a rare case of glomus tumor of Hoffa's fat pad in a 42-year-old woman. Magnetic resonance imaging findings along with the characteristic clinical picture led us to suspect a glomus tumor as the possible etiology. An ischemia test was found to be positive and this further substantiated our diagnosis. An arthroscopic excision was performed and the histology confirmed the diagnosis of g...

BACKGROUND This report describes a recurrent orbital glomus tumor in an Asian patient. CASE PRESENTATION A healthy 50-year-old Korean man had progressive right exophthalmos and a soft mass on his right lower lid for 6 months. We evaluated the mass using CT and MRI, and performed excisional biopsy and pathologic examination. Pathologically, the mass was a glomus tumor. Although proptosis of th...

Direct evidence for a specific K(+) channel underlying the resting membrane potential in glomus cells of the carotid body has been absent. The product of the human ether-a-go-go-related gene (HERG) produces inward rectifier currents that are known to contribute to the resting membrane potential in other neuronal cells. The goal of the present study was to determine whether carotid body glomus c...

Background K(+) channels of the TASK family are believed to participate in sensory transduction by chemoreceptor (glomus) cells of the carotid body (CB). However, studies on the systemic CB-mediated ventilatory response to hypoxia and hypercapnia in TASK1- and/or TASK3-deficient mice have yielded conflicting results. We have characterized the glomus cell phenotype of TASK-null mice and studied ...

Glomus tumors are benign neoplasms that arise from neuromyoarterial glomus bodies, with clinical manifestations that include acute pain, cold intolerance and tenderness. Glomus tumors may occur anywhere in the skin, soft tissue or gastrointestinal tract, but are most frequently encountered in the nail bed of the hands. The present study reports the case of a 30-year-old female with a history of...
