Glomus tumors are uncommon benign neoplasms, which rarely occur in the trachea, usually originating from the posterior wall of the distal portion. Most of tracheal glomus tumors are located in the lower two thirds of the trachea. In this article, we present a 50-year-old male patient with a glomus tumor located on the upper third of the posterior wall of the trachea. A transoral endoscopic lase...

TREK-1 is one of the important potassium channels for regulating membrane excitability. To examine the distribution of TREK-1 in the rat carotid body, we performed RT-PCR for mRNA expression and in situ hybridization and immunohistochemistry for tissue distribution of TREK-1. RT-PCR detected mRNA expression of TREK-1 in the carotid body. Furthermore, in situ hybridization revealed the localizat...

Subungual glomus tumors are rare benign tumors arising from glomus body, which often present with pinpoint pain under the nail. A case of 36-year-old female patient presented with intense pain over the right middle fingertip for 15 years is reported here. A transungular approach was taken to excise the tumor mass under local anesthesia, and histopathology reported a subungual glomus tumor. Comp...

Mediastinal glomus tumors are rarely recognized, and only seven cases have been reported in the literature. Here, we describe a rare mediastinal glomus tumor and review the characteristics of this rare clinical case. The patient was a 50-year-old female who presented with coughing for 3 months. Her chest computed tomography scan demonstrated a localized tumor in the posterior superior mediastin...

Arbuscular mycorrhizal fungi (AMF) are common and important plant symbionts. They have coenocytic hyphae and form multinucleated spores. The nuclear genome of AMF is polymorphic and its organization is not well understood, which makes the development of reliable molecular markers challenging. In stark contrast, their mitochondrial genome (mtDNA) is homogeneous. To assess the intra- and inter-sp...

BACKGROUND Glomus tumors were first described by Wood in 1812 as painful subcutaneous tubercles. It is an uncommon benign neoplasm involving the glomus body, an apparatus that involves in thermoregulation of cutaneous microvasculature. Glomus tumor constitutes 1%-5% of all hand tumors. It usually occurs at the subungual region and more commonly in aged women. Its classical clinical triad consis...

Glomus tumors are neoplasms arising from the glomus body, which regulate skin temperature. They mostly benign and present in subungual area of a distal phalanx. However, they can occur extradigital location, may not be typical intradigital tumors. This makes it difficult to diagnose We report volar tumor mimicking painful ganglion with literature review.

Glomus tympanicum is a rare tumor. It classified as tumor of auricular system but there high rate recurrence. In this article, the authors present case female patient with glomus tympanicum. The has experiences 4 times recurrence within 5 years after first diagnosis. Full text available online at https://drive.google.com/open?id=1Q_2IJ_rIGv5vRsi4acRAdgIAZlx4Uvmb
