Glomus Tumor in a Segmental Bronchus: A Case Report

Glomus tumors originate from a neuroarterial structure called the glomus body, and grow mostly in soft tissue. It is rare for glomus tumors to develop in the respiratory system. The patient of the present case had an abnormal shadow in the right lung on chest X-ray, and computed tomography (CT) findings displayed a lung tumor in the right S6. Bronchoscopy was performed for the diagnosis of the lung tumor, and a polypoid bronchial tumor was unexpectedly found to occupy the right B3. The bronchial tumor was diagnosed as a glomus tumor, and the lung tumor was diagnosed as an adenocarcinoma. The bronchial glomus tumor was cauterized by argon plasma coagulation (APC). Three weeks after the cauterization by APC, the right lower lobectomy was performed for the treatment of the lung adenocarcinoma. The patient has remained disease free for 2 years.     

Glomangiomyoma of the trachea

A glomus tumor is an uncommon soft tissue tumor that is most commonly found in the subungual area and a glomus originating in the trachea is extremely rare. Histologically and ultrastructurally, these tumors have been divided into three subtypes: classic glomus tumors, glomangiomas, and glomangiomyomas. Glomangiomyomas account for less than 10% of all glomus tumors and are the least common type. We report a case of a 54-year-old man with glomangiomyoma of the trachea who presented with stridor. We treated the tumor by segmental resection and primary repair via a transcervical approach.     

Pulmonary and mediastinal glomus tumors--report of five cases including a pulmonary glomangiosarcoma: a clinicopathologic study with literature review

Pulmonary and mediastinal glomus tumors are rare lesions, with four previously reported primary pulmonary cases and three mediastinal cases. The authors report one mediastinal glomus tumor, a locally infiltrative type, and four pulmonary glomus tumors, including the first case of primary pulmonary glomangiosarcoma. These tumors show a variety of clinical and pathologic differences from the more common cutaneous variety, including later age at presentation, larger size, and more frequent atypical/malignant features. Mediastinal and pulmonary glomus tumors both have an average patient age at presentation of 45 years. However, compared with their pulmonary counterparts, mediastinal glomus tumors are less common, more often symptomatic, and are larger (average size, 5.4 cm). Additionally, mediastinal glomus tumors more often demonstrate malignant or atypical features. Pulmonary glomus tumors average 3.3 cm in greatest dimension, with the majority measuring less than 2.5 cm. The pulmonary glomangiosarcoma presented was large, measuring 9.5 cm, and showed increased mitotic count (9 mitoses/10 high-power fields), necrosis, cytologic atypia, and was associated with disseminated disease. Regardless of clinical symptoms, histologic features, and even metastases, the vast majority of all benign and malignant glomus tumors are indolent and cured surgically, with adjuvant therapy needed only for occasional patients with more advanced disease. The four patients with glomus tumors reported are currently alive and free of disease as of last follow up. The patient with the glomangiosarcoma developed widespread metastases and died of disease 68 weeks after initial therapy.     

Successful Management of a Catecholamine-Secreting Glomus Jugulare Tumor with Radiosurgery Alone

Secretory glomus jugulare tumors are often resected surgically to control the systemic effects of the catecholamines they produce. This involves complex skull base surgery, which carries significant risks and frequent morbidity. Stereotactic radiosurgery (SRS) is a recently recognized treatment for glomus jugulare tumors, though little is known about its use in secretory tumors. Case Report A young fit patient with a catecholamine-secreting glomus jugulare tumor was treated with SRS alone and over the following 37 months her urinary catecholamine excretion fell to near normal levels, and serial magnetic resonance imaging (MRI) confirmed a reduction in tumor volume. Discussion Radiosurgery is an accepted treatment for glomus jugulare tumors and is now readily available to skull base surgeons. In this case a catecholamine-secreting tumor was successfully controlled with radiosurgery alone. Further research and long-term follow-up will determine the role of this treatment in the nonsurgical management of secreting glomus jugulare tumors.     

Glomus tumor of the penis

Glomus tumors of the penis are extremely rare. A patient with multiple regional glomus tumors involving the penis is reported. A 16-year-old boy presented with the complaint of painless penile masses and resection of the lesions was performed. The pathologic diagnosis was glomus tumor of the penis. This is the ninth case of glomus tumor of the penis to be reported in the literature.     

Multiple glomus tumor: a case report and review of the literature.

Multiple glomus tumors are extremely rare and differ from the more common solitary glomus tumors in their clinical presentation and histological features. The authors report a case of multiple glomus tumors of the right hand in a 65-year-old man, its treatment, and a review of the features of this uncommon tumor. The tumor usually presents as a painful, firm, purplish, solitary nodule of the extremities, especially in the nail bed. Multiple glomus tumors are described as softer, more compressible, bluish nodules and they occur with less frequency than solitary tumors. They are often inherited in an autosomal dominant pattern. The authors present a case of multiple glomus tumors of the right hand, in which many small, painful, red papules were grouped in the right hypothenar region. The patient was treated by wide excision of the lesion and coverage of the defect with an ulnar artery forearm flap.     

Intrapulmonary glomus tumor in a young woman

A 21-year-old female patient presented with pneumonia and on chest roentgenogram a solitary pulmonary nodule was incidentally found. After an observation period she underwent left upper lobectomy because of documented tumor growth. Pathology showed an intrapulmonary glomus tumor of the proper type, which is a very rare occurrence. Literature review revealed only 11 published cases of this subtype. Radiological investigation is helpful for localization and characterization of the tumor. However, pathological examination is required for definitive diagnosis. Complete surgical excision is the treatment of choice. Although uncommon, glomus and carcinoid tumors should be considered in the differential diagnosis of solitary pulmonary nodules in young patients.     

Glomus tumor of the glans penis

Glomus tumors of the penis are extremely rare. We report a patient with a solitary glomus tumor involving the penis. A 19-year-old man presented with a complaint of a recurrent painful penile mass. Resection of the lesion was performed. The pathologic diagnosis was glomus tumor of the glans penis. This case emphasizes the need for complete extirpation of the glomus tumor to avoid additional surgery.     

Multiple glomus tumors of the stomach with intravascular spread.

Gastric glomus tumors are characteristically benign solitary lesions. We present a case of multiple glomus tumors involving the stomach wall and perigastric adipose tissue. Histologically, the major portion of each tumor was composed of "typical" glomus cells arranged in a predominantly solid pattern. Cavernous hemangiomalike areas were present toward the periphery. The tumor cells were immunoreactive for alpha-smooth muscle actin, vimentin, laminin, and type IV collagen, but did not express desmin. There were several focal areas where the tumor cells had a signet-ring cell-like appearance, intermingled with cells having clear cytoplasm and hyperchromatic nuclei. Rare mitoses were noted. A striking feature was the presence of widespread but subtle extension of the glomocytes along venous channels subendothelially, with formation of intravascular nodules focally. The multiple separate tumor nodules found in perigastric fat are interpreted as having arisen in this manner. This entity is distinct from previously described typical and atypical solitary glomus tumors, glomangiosarcoma, and the syndrome of multiple glomus tumors of subcutaneous tissues. It may represent an early stage of development of the large, multilobulated glomus tumors that have rarely been reported to involve stomach and adjacent viscera.     

Long-term results of surgery for temporal bone paraganglioma

The only way to resolve the dispute about the effectiveness of surgery versus radiation therapy for glomus tympanicum and jugulare tumors is adequate long-term studies. In a retrospective study with an average follow-up period of 15 years (range 11 to 23 years) we reassessed 11 patients with glomus tympanicum tumors and 11 patients with glomus jugulare tumors. Ten of 11 patients with glomus tympanicum tumor were tumor-free after surgery. A temporary facial palsy and an external meatal wall defect were the only surgical complications. The air-bone gap postoperatively closed to within 10 dB in three patients, to within 20 dB in six patients, and to more than 30 dB in one patient. Nine of 10 patients with glomus jugulare tumor receiving complete resection were tumor-free. Less than half the patients experienced new-onset cranial nerve function loss, and all made satisfactory recovery, eliminating the need for tracheostomy or gastrostomy. In two patients, the hearing could be preserved on the preoperative level, but the majority already presented with deafness. In the long-term, surgery remains a treatment of choice for glomus tympanicum tumors. It is also an extremely effective treatment with low morbidity for glomus jugulare tumors, including those with intracranial extension.

Gastrointestinal glomus tumors: a clinicopathologic, immunohistochemical, and molecular genetic study of 32 cases

Glomus tumors usually occur in the peripheral soft tissues, but similar tumors have also been reported in the stomach and occasionally in the intestines. However, the relationship of these tumors to peripheral glomus tumors and gastrointestinal stromal tumors has not been fully clarified because previous series of gastrointestinal glomus tumors predate availability of immunohistochemistry. This clinicopathologic study examined 32 gastrointestinal glomus tumors. All but one of the tumors were located in the stomach and the remaining tumor was from the cecum. The tumors occurred with a strong female predominance (23 females and 9 males) and a median age of 55 years (range 19-90 years). The gastric tumors typically presented with gastrointestinal bleeding or ulcer-like symptoms, and 14 tumors had mucosal ulceration. Five tumors were incidental findings. The tumor sizes varied from 1.1 to 7 cm (median 2 cm), and most were located in the antrum. Histologically, the tumors typically had a solid pattern of sharply demarcated, round glomus cells with prominent, mildly dilated pericytoma-like vessels. Vascular invasion and focal atypia were relatively common (seen in 11 and 13 cases, respectively), and low mitotic activity (1-4 per 50 high power fields), was seen in 10 cases. Immunohistochemically, all tumors were positive for alpha-smooth muscle actin and calponin, and nearly all had a net-like pericellular laminin and collagen type IV positivity. All tumors were negative for desmin and S-100 protein. Three tumors had focal synaptophysin positivity, but none was positive for chromogranin. All tumors lacked KIT expression and the GIST-specific mutations in the c-kit gene. Follow-up revealed one patient death of metastatic disease to liver at 50 months; this tumor had 1 mitosis per 50 high power fields, but had spindle cell foci, mild atypia, and vascular invasion. Thirteen patients were well and alive after long-term follow-up. Gastrointestinal glomus tumors occur almost exclusively in the stomach, and they have a good overall prognosis, but a small, unpredictable potential for malignant behavior exists. These tumors are phenotypically similar to peripheral glomus tumors and differ from epithelioid GISTs.     

Tumeur glomique de la face postérieure du poignet : à propos d’un cas

Extra-digital glomus tumors are extremely rare and difficult to diagnose. The authors report a case of glomus tumor of the dorsal aspect of the wrist, discovered incidentally after surgical resection in a 71-year-old patient.     

Subungual glomus tumors of the fingers: ultrasound diagnosis

INTRODUCTION: Glomus tumors of the fingers are rare, benign tumors. These lesions are hamartomas, originating from dermoepidermic glomus, most commonly located at the distal phalanx, and in particular under the nail. Diagnosis is often delayed because of the absence of specific symptoms. Confirmation can only be made by histological study. The aim of this retrospective study is to define the role of ultrasound examination in the diagnosis of glomus tumors of the fingers. METHOD: During the period March 2002-March 2004, 12 cases of subungueal glomus tumors were included in this retrospective study. All patients underwent ultrasound and Doppler examinations before surgery. All Ultrasound Doppler studies were performed by the same radiologist. The mean age of patients was 44 year-old and the sex-ratio was 1/2. RESULTS: Pain was noted as a symptom in all patients. The mean size of the tumor was 3.5 mm. In eleven patients, ultrasound study was able to confirm the diagnosis, but it failed in one case because of the small size of the tumor (less than 2 mm). Ten tumors presented a Doppler hypersignal, located in the tumor and compatible with the diagnosis of glomus tumor. DISCUSSION: Diagnosis of glomus tumor is based on clinical examination, standard radiology, and ultrasound Doppler study. Ultrasound examination and Doppler study gives better visualization of tumors compared to standard radiology. These studies are useful for follow-up of patients in the post-operative period.     

The glomus tumor resorbed bone and teeth in the mandible: a case report

Background

A glomus tumor is a rare neoplasm usually found in the dermis or subcutaneous tissue of the extremities. It is rare for the glomus tumor to occur on the head and face. Only 26 glomus tumors of the oral region and affected bone have been reported in the English-language literature (Table 1). We report a case of a glomus tumor at the mandible. As a new point, the glomus tumor resorbed a bone and teeth roots when the tumor progressed into the mandible.

Case presentation

The patient was a 44-year-old Japanese man who complained swelling of the right mandible. Radiographic examination showed a multilocular radiolucency area in the left mandible. Radiographic findings on our case resembled those of a common benign tumor. The lesion occupied to the premolar and molar area and revealed that the tumor resorbed the roots of the teeth. The lesion was removed surgically with the buccal cortical bone and buccal mucosa in contact with the mass of the tumor. The mass fully excised intraorally under general anesthesia, and the inferior alveolar nerve in contact with the mass was preserved.The specimen was pathologically diagnosed as a glomus tumor. Immunohistochemical staining was positive for vimentin, muscle-specific actin/HHF35, and calponin. A hairline-shaped area of positive staining for type IV collagen surrounding the tumor cells was also observed. In contrast, staining for alpha-SMA, cytokeratin (AE1/AE3), cytokeratin (CAM5.2), CK19, CD31, CD34, CD68, p63, S-100, Factor VIII, and desmin was all negative. The Ki-67 labeling index was almost 1%.A recurrent tumor was again detected in the site below the primary tumor at an 8-year follow-up, and it was surgically removed. The patient has had no symptoms of recurrence in 2 years after the second operation.

Conclusion

The glomus tumor resorbed a bone and teeth roots when the tumor progressed into the mandible. The immunohistochemical features of the tumor were consistent with those described in previous reports. It is important to completely remove the Glomus tumor.

     

Primary fallopian canal glomus tumors

Primary fallopian canal glomus tumor has been reported only once previously, although the occurrence of glomus body tissue in the fallopian canal was documented many years ago. Facial paresis as a presenting symptom of glomus tumors is well known, as is facial nerve invasion by glomus tumors. However, a primary fallopian canal glomus tumor that extends extratemporally to the pes anserinus is unusual. Although facial nerve grafting may be necessary for removal of some glomus jugulare tumors, the need for facial nerve grafting appears to be uniform in the patients with primary fallopian canal glomus tumors. The primary fallopian canal glomus tumors that we report did not involve the jugular fossa or the Jacobson's branch of the glossopharyngeal nerve. Both tumors did extend to the middle ear and mastoid and followed the facial nerve extratemporally. The latter features appear to typify primary fallopian canal glomus tumors.     

Glomus tumors

The authors report a series of 12 consecutive patients with 13 glomus tumors operated from July 1991 until February 1999. Symptoms were present for an average of 1.9 years before surgery. Women were more frequently affected. The mean age was 44 years. In 12 of the 13, the tumor was located in the distal phalanx and one patient had a glomus tumor on the dorsum of the hand. One glomus tumor was found in the right hallux of a two-year-old child. Both hands and all fingers were equally involved. One bilateral glomus tumor was associated with neurofibromatosis. All tumors were resected and histology confirmed the diagnosis. The result was good with immediate pain relief. No recurrence has been noted to date.     

Glomus tumor of the kidney: a report of 3 cases involving renal parenchyma and review of the literature

Glomus tumor is a rare mesenchymal neoplasm affecting the subcutaneous tissue of the distal extremities in the majority of cases. It only rarely involves visceral organs. We report 3 cases of the glomus tumor family in the kidney, a solid glomus tumor, a glomangioma, and a glomangiomyoma. All 3 tumors involved the renal parenchyma and occurred in 3 men aged 36, 81, and 48 years, respectively. All 3 tumors were well-circumscribed and showed morphology otherwise identical to those seen in soft tissue. All 3 tumors were immunoreactive for actin and negative for desmin and S100 and only 1 tumor expressed CD34 in tumor cells. To date, all 3 tumors have followed a benign course without evidence of recurrence or metastasis. This report expands the spectrum of mesenchymal tumors of the kidney.
