1/29. upper extremity pain of 10 years duration caused by a glomus tumor.BACKGROUND AND OBJECTIVES: Long-standing limb pain typically has a multifactorial etiology not amenable to causal therapy. We present a case of chronic progressing upper extremity pain caused by a glomus tumor; the excision was curative. methods: A 39-year-old woman presented with 10-year history of constant deep internal throbbing, aching pain localized to the radial aspect of the left index finger and additional intermittent shooting pains radiating up the arm toward the shoulder. pain was increased after minor local trauma, following cold exposure, and for unknown reasons. A blotchy, bluish skin discoloration could appear on the radial aspect of the index finger during severe pain. Nonsteroidal antinflammatory drugs, narcotics, amitriptyline, local heat, bracing, and a sympathetic nerve block had all been ineffective. The physical examination was characterized by exquisite pressure tenderness over the radial aspect of the left index finger, most pronounced just distal to the distal interphalengeal joint. RESULTS: Inflation of a left arm blood pressure cuff to above systolic pressures abolished pain. A glomus tumor was suspected and confirmed by histologic examination. CONCLUSIONS: Glomus tumors are rare, benign neoplasms (1 to 5% of all hand tumors), developing from neuromyoarterial glomus bodies. They usually present with pain and may mimic other painful conditions, delaying the average time until diagnosis for up to 10 years. The classic diagnostic triad consists of local pain, pressure tenderness, and cold hypersensitivity. Abolition of pain following inflation of a blood pressure cuff to above systolic levels (ischemia test) is highly diagnostic. We suggest routine use of this test in cases of upper limb pain of unclear etiology.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
2/29. Glomus faciale, glomus jugulare, glomus tympanicum, glomus vagale, carotid body tumors, and simulating lesions. role of MR imaging.In summary, MR imaging characteristics of a case of paraganglioma of the facial nerve are reported. The relationship of paragangliomas and the chromaffin system have been discussed. There are many reports of cases of synchronous paragangliomas and pheochromocytomas. These reports, along with simultaneous involvement in familial men syndromes, and the common embrylogic origin (neural crest) and similar histopathologic relationships between paragangliomas and pheochromocytoma, all support the fact that they are part of the chromaffin system.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
3/29. Uncommon hand tumours.This paper presented clinical examples of some rare or uncommon presentations of tumours of the hand, including glomus tumour, intraosseous dermoid, fibrolipoma of the radial nerve, blastomycotic cyst and synovial sarcoma. Each lesion is illustrated by review of case histories, radiological and pathological features.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
4/29. A primary glomus tumour of the facial nerve canal.Glomus tumours can present in several sites in the head and neck. A red mass in the middle ear, visible on otoscopy generally indicates a glomus tympanicum or glomus jugulare. We present photographic and radiologic evidence of such a lesion arising from the course of the intra-tympanic facial nerve, the Fallopian canal, and review the differential diagnoses.- - - - - - - - - - ranking = 5keywords = nerve (Clic here for more details about this article) |
5/29. Primary glomangioma of the liver: imaging findings.Glomus organs are small arteriovenous anastomoses that are chiefly responsible for thermoregulation of the distal portion of the extremities. Glomangiomas are benign tumors of these bodies. Glomangiomas occur preferentially in the fingers and toes, but some case reports have described primary glomangiomas in the respiratory or gastrointestinal tract and the genitals. To date, no glomangiomas of the liver have been observed. We report on a 61-year-old patient in whom routine ultrasound disclosed a subcapsular well-defined mass in the liver. On imaging studies, no correspondence to the usual liver tumors was found. Magnetic resonance-guided biopsy showed a primary glomangioma of the liver. Clinically, the patient had no appetite and lost weight over several months. Due to the patient's weight loss and potential malignant transformation, the tumor was excised. Histologic work-up confirmed the diagnosis of a glomangioma with no signs of malignancy.- - - - - - - - - - ranking = 0.25454123325344keywords = organ (Clic here for more details about this article) |
6/29. Presentation of an unusual benign liver tumor: primary hepatic glomangioma.Glomus organs are small arteriovenous anastomoses chiefly responsible for thermoregulation of the distal portion of the extremities. Glomangiomas are benign tumors of these bodies. They occur preferentially in the fingers and toes, but some case reports describe primary glomangiomas in the respiratory or gastrointestinal tract and genitals. To date, no glomangiomas of the liver have been reported. We report on a 61-year-old patient in whom routine ultrasound disclosed a subcapsular well-defined mass in the liver. Further imaging showed that the mass did not correspond to any of the usual liver tumors. biopsy finally revealed it to be a primary glomangioma of the liver. Clinically, there was lack of appetite and weight loss over a period of several months. Owing to the possibility of malignant transformation of glomangiomas, as described in the literature, the tumor was excised under existing clinical symptoms and continued slow growth. Further histological evaluation of the tumor did not reveal malignancy. Primary glomangioma of the liver is a new differential diagnosis for benign liver neoplasms. Because there is a potential for malignant transformation, the existence of clinical symptoms and continuing growth are indications for resection.- - - - - - - - - - ranking = 0.25454123325344keywords = organ (Clic here for more details about this article) |
7/29. Multiple familial facial glomus: case report and review of the literature.Facial paraganglioma is an extremely rare tumor that originates from abnormal paraganglionic tissue situated in the intrapetrous facial canal. A review of the English-language literature shows that only 8 cases of facial nerve paraganglioma have been published. In each case the facial glomus presented itself sporadically, completely independent of any other form of paraganglioma. This study reports an intrapetrous facial glomus that occurred in a case of multiple paragangliomas with a hereditary pattern. To our knowledge, this is the first report of such a combination.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
8/29. Primary pulmonary glomus tumor with contiguous spread to a peribronchial lymph node.Glomus tumors are uncommon soft tissue tumors. Rare occurrences in visceral organs including the respiratory tract have been reported. The vast majority of these tumors are biologically benign. We report a case of primary pulmonary glomus tumor with atypical features characterized by mild nuclear atypia, local infiltration, and contiguous spread to a peribronchial lymph node. The current literature is reviewed.- - - - - - - - - - ranking = 0.25454123325344keywords = organ (Clic here for more details about this article) |
9/29. The value of flow cytometric analysis in multicentric glomus tumors of the head and neck.Glomus tumors of the head and neck include those arising from the carotid body, jugular vein, and vagus nerve. Because these cannot be differentiated histologically, when encountering a large tumor mass involving more than one structure in the carotid sheath, one often cannot be sure whether the tumors are from one or more of these structures. The authors performed dna flow cytometric analysis on a patient with a multicentric glomus tumor on the right side of the neck involving the carotid body, jugular vein, and vagus nerve, in an effort to determine the separate or similar origin of her tumor mass. Different dna indices, including a double peak for the carotid body tumor, were obtained. There were three aneuploid tumors and one diploid tumor (dna indices: carotid body 1.78, 2.04; jugular vein 2.20; vagus nerve 1.82). Different synthetic phase fractions were calculated for each aneuploid tumor except the second carotid body peak (carotid body 7.2; jugular vein 3.6; vagus nerve 4.8). The authors conclude that dna flow cytometry may be useful in confirming the multicentric origin of tumors that encompass more than one histologically similar structure.- - - - - - - - - - ranking = 4keywords = nerve (Clic here for more details about this article) |
10/29. Glomangioma of the upper limb associated with hypoplastic-dysplastic superficial venous system.The diagnosis and therapy of vascular malformations is difficult. An important factor, which influences the therapeutic approach, is the complicated vascular network of the lesions. The frequent involvement of various structures (muscles, bones or other organs) makes the surgical intervention arduous. Glomus tumors are rare, symptomatic (painful) lesions, with dimensions ranging 3-10 mm and usually subungual location, which need radical resection as a therapy. The case we present is the first one where a glomus tumor presents as a hypoplastic-dysplastic superficial venous system, located parallel to the normal superficial venous system of the left upper extremity, resembling a form of varicosities. The atypical clinical presentation and the unique morphology classify this case in a very limited category of nosological entities.- - - - - - - - - - ranking = 0.25454123325344keywords = organ (Clic here for more details about this article) |
