The differential diagnosis for knee pain is extensive. Glomus tumors comprise approximately 1.6% of soft-tissue tumors in the extremities. Classic subungual tumors occur more frequently in women, whereas ectopic locations are more common in men. Unusual locations include the stomach; lungs; trachea; bones; intestines; fallopian tubes; and intraneural, neuromal, and intravenous locations. We present the case of a 50-year-old man with a 12-year history of enlarging right knee mass found to be a glomangioma. This case report discusses the incidence, presentation, imaging characteristics, histology, and management of glomus tumors of the knee...

To the best of our knowledge, this is the first case report of middle ear extramedullary hematopoiesis (EMH) in a pediatric patient as well as the first bilateral presentation reported in both children and adults. We report a 13-year-old African-American female with sickle cell disease who developed bilateral hearing loss, with magnetic resonance imaging findings consistent with bilateral glomus tympanicum (GT). Upon excisional biopsy, however, EMH was diagnosed histologically. Besides its novelty, this case highlights the importance of considering EMH in the differential diagnosis of GT including cases with bilateral presentation that may be otherwise highly suggestive of the familial form of GT...

Acute oxygen (O2) sensing is essential for individuals to survive under hypoxic conditions. The carotid body (CB) is the main peripheral chemoreceptor, which contains excitable and O2-sensitive glomus cells with O2-regulated ion channels. Upon exposure to acute hypoxia, inhibition of K(+) channels is the signal that triggers cell depolarization, transmitter release and activation of sensory fibers that stimulate the brainstem respiratory center to produce hyperventilation. The molecular mechanisms underlying O2 sensing by glomus cells have, however, remained elusive...

BACKGROUND: Lignin and cellulose, organic constituents of plant or plant based material not commonly used for feeding purpose are referred as Biomass. This can be used as best resource of renewable energy. Vesicular arbuscular mycorrhizae (VAM) fungi can play an effective role in biomass manufacturing through activated metabolism of plant under dual symbiosis. During C acclimatization, mycorrhizal inoculated plants existent greater number of leaves with height of plants as compared to non-mycorrhizal plants...

The potential role of soil fungi in the invasion of the Brazilian pepper tree (Schinus terebinthifolius-BP) in Florida is not known; although the low biotic resistance of Florida soils is often invoked to explain the prevalence of many invasive species. To gain an initial insight into BP's mycorrhizal associations, this study examined the rhizobiome of BP and two native plants (Hamelia patens and Bidens alba) across six locations. Arbuscular mycorrhizal fungi (AMF) associated with the roots of the target plants and bulk soil was characterized by spore morphotyping...

Cervical metastases from breast carcinoma are extremely rare after several years of disease-free survival. In this article, a metastatic tumor of the neck originating from a breast carcinoma, which has been treated 14 years ago, is discussed. A case is presented of a 48-year-old female patient with a history of breast carcinoma, which was surgically treated approximately 14 years ago. Patient was evaluated as glomus vagale because of clinical and radiologic characteristics. The resection of the mass was performed under general anesthesia, without any complications...

Although gastric tumors have overlapping radiologic appearances, some unusual tumors may present specific imaging features. Using multidetector computed tomography (MDCT), with water as a negative oral contrast agent and intravenous contrast medium, can provide critical information for the diagnosis of gastric diseases. In addition, MDCT can evaluate the involvement of the gastric wall and extragastric extent of the disease, as compared with gastroenteroscopy and double-contrast upper gastrointestinal study...

Glomus tumors are rare neoplasms that typically occur within the dermis or subcutis of the subungual space. Primary glomus tumors of the thorax are exceedingly uncommon, thus standard-of-care management is lacking. In this report we describe the management of a patient presenting with a symptomatic glomus tumor of the posterior trachea, and provide a comprehensive review including all documented tracheal glomus tumor reports.

The pericytic (perivascular myoid cell) family of tumors is a distinctive group of mesenchymal neoplasms encountered in superficial sites and only rarely seen in viscera. The pericytic family subtends a spectrum of lesions, namely, glomus tumors and variants; myopericytoma, including myofibroma; and angioleiomyoma. In light of the contemporary classification of pericytic lesions, we identified and reviewed 17 cases of renal pericytic tumors from the files of 6 referral centers. These tumors presented over an age range of 17 to 76years (mean 46...

A glomus tumor of uncertain malignant potential is defined as a glomus tumor with some, but not all, criteria for malignancy and without a known metastasis. Here, we present a rare example presenting in the median nerve in a 40-year-old woman with a long history of severely impaired left median nerve function. A large panel of immunohistochemical stains excluded other diagnoses, and the designation of a "uncertain malignant potential" was based on the high proliferative activity, the tumor size and location, and the lack of WHO malignancy criteria such as marked nuclear atypia, necrosis, or atypical mitoses...

We report a case of tentorial dural arteriovenous fistula (DAVF) with a severe intracranial hemorrhage occurring after Onyx embolization. A 40-year-old man presented with an asymptomatic tentorial DAVF on angiography. Transarterial embolization with Onyx was performed via the middle meningeal artery, and the cast filled the fistula itself and its proximal draining vein. Postoperative angiography confirmed complete occlusion of the DAVF. A computed tomography scan performed immediately after the procedure demonstrated an acute subdural hematoma with the temporal hemorrhage...

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 expensive. Due to these limitations, we set out to establish that diagnosis and management of these rare tumours can be based solely on a battery of clinical tests and history taking...

Peanut (Arachis hypogaea Linn. cv: Luhua 11) and tomato (Lycopersicon esculentum Mill. cv: Zhongshu 4) were inoculated with arbuscular mycorrhizal fungi (AMF) Funneliformis mosseae BEG167 (Fm), Rhizophagus intraradices BEG141 (Ri), and Glomus versiforme Berch (Gv), and/or Spodoptera exigua (S. exigua) under greenhouse conditions. Results indicated that feeding by S. exigua had little influence on colonization of peanut plants by AMF, but improved colonization of tomato by Fm and Gv. Feeding by S. exigua had little influence on leaf net photosynthetic rate, transpiration rate, and stomatal conductance of nonmycorrhizal peanut plants but significantly improved net photosynthetic rate and transpiration rate of mycorrhizal plants of both hosts...

The evolutionary origins of the hypoxia-sensitive cells that trigger amniote respiratory reflexes - carotid body glomus cells, and 'pulmonary neuroendocrine cells' (PNECs) - are obscure. Homology has been proposed between glomus cells, which are neural crest-derived, and the hypoxia-sensitive 'neuroepithelial cells' (NECs) of fish gills, whose embryonic origin is unknown. NECs have also been likened to PNECs, which differentiate in situ within lung airway epithelia. Using genetic lineage-tracing and neural crest-deficient mutants in zebrafish, and physical fate-mapping in frog and lamprey, we find that NECs are not neural crest-derived, but endoderm-derived, like PNECs, whose endodermal origin we confirm...
