An oncocytic variant of glomus tumor of the trachea occurred in a 47-year-old woman. She experienced intermittent cough and hemoptysis for about three years. Bronchoscopy and chest CT scan showed a small reddish polypoid tumor on the lower end of the trachea. Bronchoscopic biopsy was carefully done and was diagnosed as oncocytoma. A wedge resection of the tumor was done. Tumor cells were charac...

A technique combining PCR and restriction fragment length polymorphism analysis was used to generate specific DNA fragment patterns from spore extracts of arbuscular mycorrhizal fungi. With the universal primers ITS1 and ITS4, DNA fragments were amplified from species of Scutellospora and Gigaspora that were approximately 500 bp long. The apparent lengths of the corresponding fragments from Glo...

A unique oligonucleotide pair, GOCC56:GOCC427, was designed that correctly primed specific amplification of a approximately 370-bp sequence spanning the ITS and 5.8S rDNA regions of Glomus occultum and Glomus brasilianum. In addition, this primer pair successfully detected G. occultum and G. brasilianum DNA in nested PCR using a primary PCR product amplified from highly diluted extracts of colo...

A 46-year-old man presented with an extremely painful, 1 cm, mobile, nodular mass located on the medial side of his right elbow. Symptoms failed to respond to conservative treatment. Ultrasound and Doppler flow imaging revealed a well-defined, round hypoechoic mass. Under local anesthesia, the mass was resected and the wound closed without complication. Final pathology diagnosed the lesion as a...

Solanum nigrum was found to proliferate in sediments with high levels of metal pollution. The effect of Zn on plant growth and tissue metal accumulation was assessed. The response of the plant to the inoculation with four different isolates of arbuscular mycorrhizal fungi (AMF) (Glomus sp. BEG140, Glomus claroideum, Glomus mosseae and Glomus intraradices) was studied. While the isolates of AMF ...

The distribution and ultrastructural characteristics of calbindin D-28k immunoreactive nerve fibers were examined in the carotid body of the normoxic control rats by light and electron microscopy, and the abundance of calbindin D-28k fibers in the carotid body was compared in normoxic and chronically hypoxic rats (10% O2 and 3.0-4.0% CO2 for 3 months). Calbindin D-28k immunoreactivity was recog...

INTRODUCTION Diagnosis of subungual glomus tumour is mostly based on detailed history and clinical examination. Recently, Magnetic Resonance Imaging (MRI) and Ultrasound have been proposed as the imaging modality to confirm the clinical diagnosis and in planning the surgical management of these tumours. However, these imaging modalities are not routinely available in rural setting and also are ...

INTRODUCTION Glomus tumors are rare neoplasms arising from the subcutaneous glomus apparatus. They account for 1 - 5% of the soft tissue tumors of the upper extremity, occurring in most cases in the nail bed. The typical clinical presentation includes paroxysmal pain and hypersensitivity to cold which limit the use of the affected hand causing practical, professional and often emotional discomf...

Two new families with glomus tumours and two additions to earlier publications are presented. The pattern of inheritance is autosomal dominant. Familial glomus tumours are inherited almost exclusively via the paternal line, a finding inconsistent with autosomal dominant transmission. This can be explained by genomic imprinting. The maternally derived gene is inactivated during female oogenesis ...

Glomus tumors derive from the glomus cell around arteriovenous anastomosis. These are rare tumors and when found are most common in the deep dermis of the extremities. In rarer cases still they have been reported to be found in the lung. These are most commonly incidental findings of solitary lesions of the lung with a pre-operative differential diagnosis of non-small cell carcinomas and carcin...
