BACKGROUND AND AIMS: To evaluate contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) for the differential diagnosis of submucosal tumors (SMT) of the upper gastrointestinal tract. METHODS: Between June 2008 and May 2015, 157 consecutive patients with submucosal lesions of the upper gastrointestinal tract were evaluated by CH-EUS. This was a single-center retrospective analysis of prospectively collected data in a registry. The data from 73 patients who later underwent surgical resection were analyzed in this study...

Glomangiosarcoma represents a rare malignant variant of the benign glomus tumor that typically presents as a tender, slowly growing nodule with a predilection for the lower extremities. Unlike their benign counterparts, glomangiosarcomas may display aggressive characteristics such as large size, local invasion, and a tendency to recur after excision. Although wide local excision remains the treatment of choice, rare cases of systemic metastasis have been previously reported. We present a case of glomangiosarcoma arising at a prior biopsy site after excision of an unknown soft tissue lesion...

Glomus tumors are benign, painful growths originating from glomus bodies and comprise just 1% of tumors arising in the hand, with fewer than 10% in the volar pulp of digits. Hallmark symptoms of glomus tumors include hypersensitivity to cold, heightened pinprick sensitivity, and paroxysmal pain. We report a 72-year-old, right-hand dominant man who presented with pain in the left middle finger, localized to the tip. The fingertip was incredibly sensitive to touch, and his pain increased at night. He reported no recollection of trauma...

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...

The study presented a case of a patient with a glomus tumor of the stomach, a mesenchymal neoplasm manifesting with upper gastrointestinal bleeding (Forrest IB). The patient was operated twice. First, he underwent elective laparotomy, during which Billroth I (Rydygier's method) gastric resection was performed. This his was followed by Billroth II resection with Braun's anastomosis. Histopathological examination revealed glomus tumor tissue. Literature data on the glomus tumor of the stomach are presented.

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 mediastinum. Intraoperatively, we found a longitudinal rupture of the membranous trachea above the carina. We completely resected the tumor and repaired the tracheal rupture under a thoracoscopy using a pedicled muscle flap...

INTRODUCTION: Glomus body is an apparatus present in the skin at the arterio-venous junction whose main function is to control the body temperature. Hyperplasia of the glomus body results in an entity called glomus tumor. Masson described this entity first in 1924, as a tumor of the neuromyoarterial body. Due to its symptoms, it is of ten misdiagnosed and wrongly treated which adds burden to the patient. CASE REPORT: We report a rare case of glomus tumor presenting at an unusal site that is the thenar eminence of the palm...

Glomus tumors arising in the urinary bladder are extremely rare, and only two cases have been reported in the English Literature. We present a case of a 58-year-old man with an asymptomatic mass of the anterior wall of the bladder that measured 2.5 × 2.5 cm. Endoscopic excision was performed, and the tumor was diagnosed as symplastic glomus tumor. The patient finally underwent robotic-assisted partial cystectomy, and he remains healthy without any recurrence to date.After reviewing this case and previous reports, we analyzed the clinicopathologic features and treatment options for this rare neoplasm...

Our aim was to identify pericyte-specific markers for the analysis of formalin-fixed paraffin-embedded (FFPE) human tissue samples, and to characterize perivascular myoid cell neoplasms phenotypically. Previously identified pericyte markers failed to distinguish pericytes from other cellular types, such as vascular smooth muscle cells (vSMCs) and fibroblasts, in immunohistochemical (IHC) analysis. However, we compared gene expression profiles between pericytes, vSMCs, and fibroblasts, and performed human skin vasculature IHC analysis, which led to the identification of myosin 1B (MYO1B) as a novel pericyte marker...

Glomus tumors are uncommon, benign, small neurovascular neoplasms derived from glomus bodies in the reticular dermis. Glomus bodies are found throughout the body to regulate body temperature and skin circulation; however, they are concentrated in the fingers and the sole of the foot. The typical presentation is a solitary nodule in the subungual or periungual area of the distal phalanx. The primary treatment of choice is surgical removal. We investigated expression of vascular endothelial growth factor (VEGF) using immunohistochemistry in glomus tumors of the fingers...

We report a case of a 76-year-old man that referred to our hospital because of progressive mixed right hearing loss, aural fullness and pulsatile tinnitus synchronized with heart beats. Otoscopic examination revealed a reddish pulsatile mass beyond tympanic membrane. CT and MRI scans showed a class C glomus tumor. Anamnesis and a complete physical examination, with careful differential diagnosis, should be obtained to rule out highly vascularized middle ear lesion before any invasive procedure.

Cholesterol granuloma (CG) is the most common benign lesion of the petrous apex, however, it can grow significantly large and become destructive causing a diagnostic dilemma. This case presents a 25-year-old female with 2-year history of left-sided progressive and profound hearing loss, a transient left-sided facial paralysis and cranial nerve 10 palsy who presented with a blue middle ear mass. Her diagnosis did not become apparent until direct visualization intraoperatively. The objective of this case study is to highlight the destructive capabilities of CG and the importance to keep it in the differential diagnosis of a large, erosive, expansile skull base lesion in order to avoid overly aggressive resection or other unnecessary treatment...

We retrospectively collected cases of surgically proven extradigital glomus tumor (EDGT) and reviewed their demographic, clinical, and sonography features. A total of 18 single, subcutaneous EDGTs were gathered. All but one were located in the extremities. EDGTs typically appear as a small, hypoechoic, homogeneous, or slightly inhomogeneous, well-delimited nodule, disposed horizontally and painful under probe pressure. Intranodular vascularization is always present. Feeding artery and efferent vein are typical but inconstant findings...

INTRODUCTION: Tumors affecting structures in the vicinity of jugular foramen such as glomus jugulare require microsurgical approach to access this region. These tumors tend to alter the normal architecture of the jugular foramen by invading it. Therefore, it is not feasible to have correct anatomic visualization of the foramen in the presence of such pathologies. Hence, a comprehensive knowledge of the jugular foramen is needed by all the neurosurgeons while doing surgery in this region...
