Glomangioma of the trachea: A case report and literature review

Tracheal Glomus Tumor: A Case Report with CT Imaging Features

BACKGROUND AND OBJECTIVES

Glomus tumors are rare benign tumors. The majority of them affect the skin the most and are rarer in the trachea, where the glomus bodies may not be present. Only scarce reports of tracheal glomus tumors have been reported solely with case reports of relevant articles.

MATERIALS AND METHODS

A 53-year-old man, with a free previous medial history, presented to our hospital with tracheal mass which was incidentally found. He did not complain of any specific symptoms associated with the tracheal tumor. The contrast-enhanced chest computed tomography (CT) revealed an avid enhancing nodular lesion, which is similar to blood vessels, in the trachea, 3 cm above the carina level without definite airway obstruction.

RESULTS

Successful tracheal resection and end-to-end anastomosis were performed on the patients; therefore, the final post-operative pathologic findings revealed a benign tracheal glomus tumor. The follow-up CT scan four months after operation showed complete removal of the tumor.

CONCLUSION

Tracheal glomus tumors, even rare entities, could be considered as a differential diagnosis if a highly enhancing mass appears on CT images.

Glomus tumor of the trachea - Synopsis of histology & methodology of treatment

Glomus tumors are neoplasms arising from modified smooth muscle cells surrounding arteriovenous anastomosis in the dermis and subcutaneous tissues, which are contributing to blood flow regulation and temperature control on the skin surface. Glomus cells are sparse or absent in visceral organs, making extracutaneous presentation of glomus tumors an extremely rare finding. We briefly report histological considerations on glomus tumors of the trachea and sum the multidisciplinary aspects of their staged endoscopic and surgical management using the example of a rare case presentation.

Treatment of primary tracheal glomus tumors: Two case reports and a literature review

RATIONALE

Glomus tumors (GTs) are rare soft tissue neoplasms. Several treatment options have been reported for tracheal GTs including thoracotomy, bronchoscopic electrocautery, Nd: YAG laser, and cryotherapy. However, few studies have evaluated the ideal treatment for tracheal GTs.

PATIENT CONCERNS

A 30-year old man who presented with cough, and expectoration for 1 month, and who had been diagnosed as having a tracheal neoplasm by cervical, and thoracic computed tomography (CT). The patient was a47 years old man. He was admitted to our hospital presenting with intermittent hemoptysis for 3 years. Thoracic CT revealed a round tumor on the right posterior tracheal wall.

DIAGNOSES

Both of them were diagnosed as benign GTs. Histopathology of the tumor showed clusters of round epithelioid cells with eosinophilic cytoplasm, and uniform round to ovoid nuclei surrounding dilated capillaries. Immunohistochemical staining was positive for smooth muscle actin (SMA).

INTERVENTIONS

The tracheal tumor of first patient was located at the level of C7-T1. Tumor resection was performed under fiberoptic bronchoscopy. The tracheal tumor in second patient was located in the lower trachea. Surgical tracheal resection and anastomosis were performed.

OUTCOMES

Both of them achieved good results and no recurrence was seen at the final follow-up LESSONS:: We recommend choosing the most appropriate approach to manage tracheal GTs based on patients' general condition, and tumor characteristics to obtain an excellent prognosis. Our 2 cases of tracheal GT were managed by different approaches, and both achieved good results.

The mimic of tracheal carcinoid in elderly female

We present a case of a glomus tumor of trachea in an elderly female who presented with a mass originating from the posterior trachea. She underwent rigid bronchoscopy with tumor debulking combined with laser therapy. Frozen section initially suggested carcinoid tumor but later turned out to be a glomus tumor. She improved with additional laser therapy. We present her clinical course and a literature review on glomus tumor.

Glomangioma of the Kidney: A Rare Case of Glomus Tumor and Review of the Literature

Background

Glomus tumors are rare mesenchymal tumors originating from glomus bodies in the skin. Glomus tumors of the kidney are rare tumors and only a few cases have been reported in the medical literature. An extensive search revealed a very limited number of primary renal glomus tumors. Although most of these cases were benign in nature, including a case with uncertain diagnosis of malignant potential, two were malignant.

Case Report

We present a unique case of a 57-year-old male patient with an incidentally discovered 2 cm left renal mass. Histopathology examination and immunohistochemical studies confirm the diagnosis of glomangioma (a form of glomus tumor). The patient was followed for one year after partial nephrectomy and showed a benign course without any evidence of local recurrence or metastasis.

Conclusion

To the best of our knowledge, this is the 16th case of primary benign renal glomus tumors. Primary renal glomus tumors are rare and may mimic other mesenchymal renal neoplasms radiologically. Proper investigation (including histopathological analysis and immunohistochemical staining) of kidney tumors is essential to make the diagnosis of glomus tumors, which usually show a benign clinical course following resection.

Tracheal Glomus Tumor: A Case Report and Review of the Literature

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.

Malignant glomus tumor of trachea: a case report with literature review

Glomus tumors of the trachea are extremely rare and generally benign, with very few cases of malignant transformation reported in literature. We present the case of a 74-year-old man explored for cough and dyspnea. Bronchoscopy showed a polypoid mass arising from the posterolateral tracheal wall. Computed tomography demonstrated a mid-tracheal tissular mass obliterating the tracheal lumen. Resection and anastomosis of the trachea were performed. The histological and immunohistochemical findings were consistent with malignant glomus tumor.

Concomitant tracheal and subcutaneous glomus tumor: Case report and review of the literature

Glomus tumors are unusual and generally benign neoplasms mainly found in subungeal areas. We describe a case of concomitant subcutaneous and tracheal glomus tumor that underwent successful endoscopic resection. A 48-year old male with a left forearm subcutaneous mass presented with hemoptysis. A chest CT scan demonstrated a polypoid tracheal lesion. He underwent a bronchoscopic resection. A biopsy revealed a glomus tumor, which was the same type of neoplasm that was found on the forearm biopsy. Glomus tumors are rarely found in the respiratory tract. Only 49 cases have been described. The majority of the glomus tumors arise from the lower posterior tracheal wall with no extraluminal extension. Bronchoscopic resection has been successfully used. Glomus tumors should be included in the differential diagnosis of tracheobronchial lesions. Bronchoscopic resection and adjuvant radiotherapy are valid treatment options. This is the first report of concomitant subcutaneous and tracheal glomus tumor, as well as the first reported airway glomus tumor, in Latin America. As part of this study, we also perform a literature review.

Glomus tumor of the trachea: a rare case report

A tracheal glomus tumor is extremely rare. There were approximately 18 reported cases before in China. Here we report a 48-year-old male with glomus tumor of the trachea. The computed tomography (CT) scan of the chest showed a nodulein the basalsegmentof right lower lobe, focal uplift in the left-posterior wall of the trachea, measured 1.5×1.2×1.0 cm. Microscopically, the tumor tissue was rich with vessels, shaped flake-nest, and the tumor consisted of a sheet of uniform cells surrounding the vascular spaces. Immumohistochemical staining were positive for SMA, vimentin, collagen IV, CD34, the Ki-67 proliferation activity was low (<1%), and were negative for Syn, CgA, S-100, AE1/AE3 and EMA. PSA staining showing clear cell borders. With a review of the literature, the clinical, pathological characteristics and treatment modalities of this rare tumor are discussed.
