We report a 38-year-old woman with a left lung tumor presenting as obstructive pneumonia. Bronchoscopic examination revealed a polypoid tumor filling the left main bronchus. The tumor was partially resected by a snaring procedure for diagnostic purposes. Microscopic examination revealed a submucosal tumor located underneath normal bronchial epithelium. The tumor was composed of sheets of unifor...

PURPOSE We examined other middle ear locations of glomus tympanicum tumors, which arise from glomus bodies accompanying the tympanic (Jacobson's) nerve through the middle ear. Most descriptions place these tumors on the promontory over the basal turn of the cochlea. METHODS We identified seven patients (all women) with small surgically confirmed glomus tympanicum tumors (not completely fillin...

Glomus tumor is an exceedingly rare neoplasm that is derived from cells of the neuromyoarterial glomus or glomus body. It rarely occurs in the visceral organs where glomus body may be sparse or even absent, such as the stomach, intestines, mediastinum, and respiratory tract. It is unusual for a glomus tumor to demonstrate atypical or malignant histopathological characteristics. It is also rare ...

OBJECTIVE The aim of this study was to investigate the value of color Doppler flow imaging (CDFI) in the diagnosis of glomus tumors in the extremities. METHODS Sonography results of 62 nodules of 50 patients with glomus tumors in the extremities confirmed by surgery and pathology were analyzed retrospectively. RESULTS The sex ratio in the group of 50 patients was (female:male) = 5.25:1. Glo...

Introduction. Glomus tumors (GTs) are benign neoplasm originating from the glomus body, commonly described in subungual region. The involvement abdominal is rare. Our aim is to describe a case of glomus tumor of the stomach that presented upper gastrointestinal bleeding. A 34-year-old woman was admitted with upper gastrointestinal bleeding and underwent an upper endoscopy that showed bleeding a...

BACKGROUND Glomus tumours are neoplasms arising from cells of the neuromyoarterial glomus bodies, which almost always occur in a subungual location. A lung location is extremely rare, with few cases reported in the literature. CLINICAL CASE The case is presented of a 33 year-old male, with non-productive cough, dyspnoea at rest, intermittent fever, and mild pain in rib cage. A chest radiograp...

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...

We have tested the suitability of chromaffin-like carotid body glomus cells for dopamine cell replacement in Parkinsonian rats. Intrastriatal grafting of cell aggregates resulted in almost optimal abolishment of motor asymmetries and deficits of sensorimotor orientation. Recovery of transplanted animals was apparent 10 days after surgery and progressed throughout the 3 months of the study. The ...

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...
