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...

Authors present complex multistage endovascular treatment of female patient with an intradural infiltrative, inoperable tumor of the glomus jugulare, a stenosis of the internal carotid artery and an aneurysm of middle cerebri artery. In the literature our case report is the first announcement in which three pathology coexist ipsilateral in one patient and the patient has been treated step by step by endovascular procedures. Beside the endovascular treatment steps they display glomus jugulare tumor's symptoms, staging, treatment options and also the current treatment guidelines of internal carotid artery stenosis and intracranial aneurysms...

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...

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 endoscopic ultrasonography (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, there is no need for endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). Ectopic pancreas and glomus tumors, which originate from the third and fourth layers, are frequently seen in the antrum. However, ectopic pancreas located in the fundus or body is large and originates from the third and fourth layers (thickening of fourth layer)...

BACKGROUND: 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 most patients undergoing bilateral resection of carotid body tumors, a condition known as baroreflex failure syndrome (BFS) develops after resection of the second tumor characterized by headache, anxiety, emotional lability, orthostatic lightheadedness, hypertension, and tachycardia...
