Various types of tumor can occur in the subungual space, including glomus tumors, subungual exostosis, hemangioma, epidermal cysts, and malignant tumors. While fibromatosis can occur at various sites throughout the body, it is very rarely seen in the toe. Here, we are the first to report a case of superficial fibromatosis mimicking a glomus tumor in the subungual space of the second toe. The pr...

Glomus tumours are benign lesions occurring essentially in the hand, with a predilection for the subungueal area. Even though they have been reported in literature, extradigital localisations of glomus tumours are frequently misdiagnosed; they never lead to bone osteolysis. We report the case of a patient who presented with a typical patellofemoral syndrome due to a glomus tumour that eroded th...

Glomus tumors are small vascular tumors that are usually benign and rarely occur. They originate from glomus bodies and present in the reticular dermis. They are clinically distinguished by their small size and their ability to cause extreme pain. Most of these tumors are subungually located. However, atypical locations of the tumors sometimes cause misdiagnosis, particularly when the lesion is...

Chronic shoulder pain can be caused by muscle, bone and joint inflammatory and tumoral lesions; however, chronic shoulder pain secondary to benign vascular tumor called glomus tumor is an extremely rare occurrence. To the best of our knowledge less than 15 cases of chronic shoulder pain have been reported secondary to glomus tumor. Herein we report our experience with a young lady who presented...

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...
