Our objectives in reporting this case series are to familiarize readers with the rare occurrence of paragangliomas originating along the facial nerve and to provide a literature review. We describe 3 such cases that occurred at our tertiary care academic medical center. Two women and 1 man presented with a tumor adjacent to the vertical segment of the facial nerve. The first patient, a 48-year-old woman, presented with what appeared to be a parotid tumor at the stylomastoid foramen; she underwent a parotidectomy, transmastoid facial nerve decompression, and a shave biopsy of the tumor...

Background: Intravenous glomus tumors are extremely rare. Methods: We report a patient with an intravenous glomus tumor within a venous aneurysm misdiagnosed as a neuroma of the lateral antebrachial cutaneous nerve, based on clinical exam, electrodiagnostic studies, and findings on a magnetic resonance imaging neurogram. Results: After surgical resection, the patient's symptoms, including pain and localized hypersensitivity, totally resolved. Conclusions: This case illustrates 2 important points. First, unlike extradigital glomus tumors, magnetic resonance imaging is not reliable in diagnosing intravenous glomus tumors...

PURPOSE: To determine the risk of radiation-induced tumors or malignant transformation after single-fraction intracranial stereotactic radiosurgery (SRS). METHODS AND MATERIALS: We performed a retrospective review of 1837 patients who received single-fraction SRS for arteriovenous malformation or benign tumor (meningioma, vestibular schwannoma, pituitary adenoma, glomus tumor) at a single center between 1990 and 2009. Patients were excluded if they refused research authorization (n=31), had a genetic predisposition to tumor development (n=84), received prior or concurrent radiation therapy (n=79), or had less than 5 years of imaging follow-up after SRS (n=501)...

Glomus tumor is a rare benign vascular hamartoma derived from the modified smooth muscle cells of the glomus body. Paroxysmal pain is the leading symptom. A 78-year-old woman presented at our clinic with a 50-year history of a slow growing painful purple blue tender nodule under the right fourth finger nail. Dermoscopy and magnetic ressonance confirmed the presence of a large subungual tumor and total surgical excision was performed after partial nail plate avulsion. Histologic examination confirmed a glomus tumor...

Glomus tumors are hamartomas, which tend to occur in sites rich in glomus bodies, such as the subungual regions of digits or the deep dermis of the palm, wrist, forearm, and foot. Very rarely, they may involve peripheral nerves. We describe a patient, who, following surgical resection of a solitary glomus tumor of the left distal sciatic nerve in his teens, had recurrence with development of multiple tumors in the course of the nerve over several years. To our knowledge, this is the only known case of glomangiomatosis involving a major peripheral nerve...

Vagal paragangliomas are rare benign tumors accounting for only 3% of head and neck paragangliomas and arise from vagal ganglions, predominately the nodose ganglion in the carotid sheath. Imaging plays an important role in their diagnosis, differentiation from more common lesions presenting in the carotid space, and management. MRI is the method of choice for investigation when paragangliomas are clinically suspected. The typical salt-and-pepper appearance in T1-weighted images is well known but not specific to paragangliomas...

Using EUS, it is practicable to diagnose Subepithelial lesions (SEL) with originating layer, echo level, and internal echo pattern etc. Lipoma, lymphangioma, and cyst have characteristic features, therefore they have no need for EUS-FNA. Ectopic pancreases and glomus tumors, which are originated from 3(rd) and 4(th) layer, are frequently seen in the antrum. Although ectopic pancreases located in the fundus or body are large and originated from 3(rd) and 4(th) layer (thickening of 4(th) layer). Each Subepithelial lesions has each characteristic finding...

Carotid body paragangliomas are rare, usually benign, tumors arising from glomus cells of the carotid body. Bilateral involvement is present in ∼5% of sporadic cases and up to one-third of familial cases. In the majority of patients undergoing bilateral resection of carotid body tumors (CBTs), a condition known as baroreflex failure syndrome (BFS) develops following resection of the second tumor characterized by headache, anxiety, emotional lability, orthostatic lightheadedness, hypertension, and tachycardia...

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...

The objective of this study was to evaluate the role of removing middle ear paragangliomas using an ultrasonic aspirator (UA) through a transcanal, exclusively endoscopic approach. Three consecutive patients undergoing transcanal endoscopic resection of middle ear paragangliomas using an UA were retrospectively studied. The primary outcome measure was achieving gross total tumor resection. Secondary outcomes included postoperative hearing and early convalescence. Two glomus tympanicum tumors and one small glomus jugulare were included, and complete tumor resection was achieved endoscopically in all cases...

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...

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...
