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

Case Report: The first case of primary pulmonary collision tumor comprising mixed squamous cell and glandular papilloma and glomus tumor

A collision tumor is a rare entity, particularly if occurring in the lung. We report a case of a 57-year-old woman with a primary pulmonary collision tumor comprising mixed squamous cell and glandular papilloma (MSGP) and glomus tumor (GT). An abnormal mass was discovered in the right lung by computed tomography (CT) of the chest. A right lower lobectomy with mediastinal lymph node dissection was performed. Histological examination of the surgical specimen suggested that the lung cancer was composed of two neoplastic components. To the best of our knowledge, this is the first report of a primary pulmonary collision tumor comprising two benign tumors of different origins, which were MSGP and GT.

Endobronchial Glomus Tumor in a Child

Glomus tumors (GTs) are rare, usually benign, mesenchymal neoplasms typically located in the cutaneous tissues of the extremities. Visceral locations have been reported in ∼5% of cases. The average age at diagnosis is 42 years. GTs originating in the respiratory tract of pediatric patients are exceedingly rare. We report a 16-year-old male with a GT of the right lower lobe bronchus.

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.

Glomus tumors of the trachea: 2 case reports and a review of the literature

Glomus tumors (GTs) of the trachea are very rare neoplasms that usually arise from the distal portion of the respiratory tree. The origin of these tumors is modified smooth muscle cells of glomus bodies. In this study, we describe two cases of GT of the trachea, as well as the histologic features of these tumors and their treatments. One tumor was diagnosed via bronchoscopic biopsy, and the other tumor was diagnosed via surgery. Clinical follow-up showed that the two patients are alive and well after 8 and 15 months post-treatment, respectively. We also review the literature regarding GTs and discuss the clinical presentation, histologic features, differential diagnosis, treatment and prognosis of these tumors.

Glomus tumor in teen and repetition pneumonia: Case report

Glomus tumors are uncommon tumors that are originated from smooth muscle cells of the neuromioarterials glomus bodies located in the arteriovenous anastomoses subcutaneous tissue or deep dermis of the extremities, mainly in the palms of the hands, wrists and subungual areas of the fingers.

Carcinoid tumor, as the glomus tumor, can show an organoid pattern, increased vascularity, and uniform, round cells with eosinophilic cytoplasm, but usually are positive for cytokeratin and always stained with chromogranin and synaptophysin showing negative for smooth muscle markers which is presented in our case.

Glomus tumors have a good prognosis and surgical resection is the treatment of choice. In our case, the patient underwent pulmonary bilobectomy because of the location of the tumor in the transition between the middle lobe and the basal bronchial trunk right lower lobe divisions.

It is presented thus a glomus tumor with exceptional localization (pulmonary and bronchial) of benign histological features, according to most of the cases reported in the literature emphasizing their particular rare location, histological, and immunohistochemical profile, which helps the differential diagnosis with other most common tumors of bronchial location.

Primary pulmonary glomus tumor of uncertain malignant potential: A case report with literature review focusing on current concepts of malignancy grade estimation

We report a 38-year-old woman with a left lung tumor presenting as obstructive pneumonia. Bronchoscopic examination revealed a polypoid tumor filling the left main bronchus. The tumor was partially resected by a snaring procedure for diagnostic purposes. Microscopic examination revealed a submucosal tumor located underneath normal bronchial epithelium. The tumor was composed of sheets of uniform oval to cuboidal cells encompassing numerous blood vessels. Immunohistochemically, the tumor cells exhibited smooth muscle markers, but were negative for neuroendocrine markers. The diagnosis of primary pulmonary glomus tumor was therefore made. Subsequent bronchoscopic intervention allowed us to pin-point the origin of the tumor: superior segmental B^6a/b. She underwent a left lower lobe superior segmental resection successfully. Glomus tumors are relatively rare soft tissue tumors, and those of bronchopulmonary origin are exceedingly rare clinical condition. Among primary lung tumors, the carcinoid tumor is a mimic of the glomus tumor, and differentiating these tumors is known to be difficult, especially using small biopsy samples. In the present case, a large tissue sample obtained by bronchoscopic snaring was quite useful for the correct preoperative diagnosis. Because of the disease rarity, malignancy grade estimation of visceral glomus tumors has not been clearly addressed. Recently, the histopathological diagnostic criteria for malignant glomus tumors was defined in the WHO classification of soft tissue and bone tumors 4th edition. Here we also reviewed the literature on primary bronchopulmonary glomus tumors with special attention to the current concept of malignancy grade estimation.
