Case Report
Glomus Tumor of the Trachea: Value of Multidetector Computed Tomographic Virtual Bronchoscopy

https://doi.org/10.4065/79.2.237Get rights and content

Glomus tumor of the trachea is extremely rare. We report a case of tracheal glomus tumor in a 39-year-old man who presented with hemoptysis. The diagnosis was made after bronchoscopic biopsy of a tumor involving the posterior wall of the upper trachea. Thin-section multidetector computed tomography of the chest was performed before surgical resection, with multiplanar re-formations and 3-dimensional virtual bronchoscopic reconstruction. Tracheal sleeve resection with reconstruction was successful, and pathological studies confirmed complete resection and the diagnosis of glomus tumor. The patient was disease-free 3 months postoperatively. To our knowledge, this is the first reported case in which additional computed postprocessing was used to help evaluate the extent of such a tumor.

REPORT OF A CASE

A 39-year-old man was referred to our institution for evaluation of a glomus tumor of the trachea. He had had hemoptysis intermittently for 2½ years before diagnosis of the tracheal tumor. Initially, the hemoptysis was attributed to gastroesophageal reflux with esophageal erosions. The patient underwent esophageal dilation and was treated with a proton pump inhibitor. Seven months before referral, screening CT of the chest showed a tracheal mass. Bronchoscopy revealed a 1.4-cm polypoid tumor

DISCUSSION

Tracheal tumors are rare, and most are malignant.4 Endoscopic examination is the most reliable means of establishing the diagnosis and should be performed in patients suspected of having such tumors to confirm the diagnosis and guide management.4

First described by Masson5 in 1924, glomus tumors consist of cells that resemble the modified smooth muscle of the normal glomus body.1 According to the new World Health Organization classification of tumors,6 they can be divided into 3 broad groups on

      Unusual sites of origin have included the stomach, mediastinum, vagina, penis, lung and trachea.2,3 Glomus tumors of the trachea are distinctly rare; to our knowledge only 17 cases, including this one, have been reported in world-literature so far.2,4 In the cases reported in literature (Table 1) all tumors arise from the posterior wall of the trachea and most are in the lower two thirds of the trachea.

      It also helps to locate the position of the tumor and the amount of the trachea that will need to be resected for complete excision. Moreover, patency of airways distal to an obstruction can be assessed better than with fiberoptic bronchoscopy.10,11 Fiberoptic bronchoscopy remains the gold standard to confirm a specific pathologic diagnosis.5,12
