The term glomus tumor is used to characterize two phenotypically different types of tumors: cutaneous glomangioma and paraganglioma. Both tumors can occur in a familial setting with an autosomal dominant pattern of inheritance. However, they are of different histopathologic origin. Paragangliomas derive from the APUD cell system, whereas cutaneous glomangiomas originate from glomus bodies of th...

Glomus tumors are rare hamartomas that originate from the glomus body. These tumors can be divided into solitary and multiple, the latter also known as glomangioma. We report the case of two patients with a rare variety of glomangioma called congenital plaque-like glomangioma. It presents as numerous red to bluish compressible papules, that increase in size in proportion with the weight and hei...

When de Castro entered the carotid body (CB) field, the organ was considered to be a small autonomic ganglion, a gland, a glomus or glomerulus, or a paraganglion. In his 1928 paper, de Castro concluded: "In sum, the Glomus caroticum is innervated by centripetal fibers, whose trophic centers are located in the sensory ganglia of the glossopharyngeal, and not by centrifugal [efferent] or secretom...

Study Design: A rare case report in a male and review of literature. Objectives: To describe a case report of invasive glomus jugulare tumor with intracranial extension. Methods: A 35 year old male complaint of pulsating tinnitus on his left ear, vertigo and progressive ipsilateral hearing loss for 4 years. Audiological examination and radiological assessment including Computerized Tomography a...

and inoculation with the arbuscular mycorrhizal fungi Glomus mosseae (Nicol. and Gerd.) Gerdmann and Trappe, Glomus intraradices Schenck and Smith or Glomus viscosum Nicolson on shoot apical growth of plantlets that had been micropropagated from MM 106 apple (Malus pumila L.) and Mr.S. 2/5 plum (Prunus cerasifera Ehrh.) rootstocks. Unfertilized and non-mycorrhizal plantlets showed no apical gro...

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 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...
