1/14. Tracheobronchial glomus tumor.

    Glomus tumors are uncommon. A review of the literature for tracheobronchial glomus tumors revealed 13 tracheal glomus tumors. The diagnosis may be elusive and so the true incidence of tracheobronchial glomus tumors may be greater than that reported. Three of the 14 glomus tumors were initially believed to be carcinoid. Glomus tumors should be included in the differential diagnosis of tracheobronchial tumors.

2/14. glomus tumor of the trachea.

    Extracutaneous glomus tumors are unusual and their occurrence in the trachea has been recognized with extreme rarity. We present a case of surgically resected glomus tumor of the trachea in a 34-year-old man who presented with hemoptysis and who was initially diagnosed as having a carcinoid tumor.

3/14. glomus tumor of the trachea.

    Extracutaneous glomus tumors are uncommon and rarely occur in the trachea. We describe a 73-year-old man with a glomus tumor of the trachea who presented with cough, dyspnea, chest pain, and hemoptysis. A curative segmental tracheal resection with primary reconstruction was performed with no recurrence at 6-year follow-up. The clinicopathologic features of this unusual neoplasm are discussed with a review of the literature.

4/14. glomus tumor of the trachea.

    glomus tumor of the trachea is extremely rare. There were approximately 15 reported cases before. Herein, we report another case of glomus tumor of the trachea in a 50-year-old woman presenting with cough and dyspnea for 8 years. She suffered from hemoptysis for 1 day before this admission. bronchoscopy and CT scan showed a polypoid tumor protruding into the tracheal lumen and with extraluminal extension. The tumor was located at 9 cm below the vocal cord and 1.5 cm above the carina. It measured 2.5 x 2.5 x 2.0 cm and arose from the posterior wall of the trachea. Microscopically, the tumor consisted of a sheet of uniform cells surrounding the vascular spaces. Only few scattered tumor cells showed weak positive staining for muscle actin (HHF-35) by immunohistochemical stain. Ultrastructural study confirmed the presence of small amount of myofibrillar bundles with focal densities in some of the tumor cells. Other cells exhibited only rare or very sparse myofilaments. Characteristic feature of fine pinocytotic vesicles along the plasma membrance of the tumor cells was also noted.

5/14. glomus tumor of the trachea: value of multidetector computed tomographic virtual bronchoscopy.

    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.

6/14. Glomus tumour of the trachea: report of a case with microscopic, ultrastructural and immunohistochemical examination and review of the literature.

    A case of glomus tumour of the trachea is reported. The patient, a 58-year-old man, complained of dyspnoea, cough and occasional haemoptysis for many years and had been misdiagnosed as having chronic bronchitis. The diagnosis of glomus tumour in a tissue sample taken by bronchoscopy was useful in planning adequate surgery. light and electromicroscopy of the excised tumour confirmed the preoperative diagnosis. Immunohistochemical examination showed vimentin and actin in the tumour cells, and negativity for high and low molecular weight keratins, desmin, neurofilaments, and factor viii-related antigen, findings similar to glomus tumours of other sites.

7/14. Oncocytic glomus tumor of the trachea.

    An oncocytic variant of glomus tumor of the trachea occurred in a 47-year-old woman. She experienced intermittent cough and hemoptysis for about three years. bronchoscopy and chest CT scan showed a small reddish polypoid tumor on the lower end of the trachea. Bronchoscopic biopsy was carefully done and was diagnosed as oncocytoma. A wedge resection of the tumor was done. Tumor cells were characterized by strongly eosinophilic granular cytoplasm on light microscopy and by numerous closely packed round or ovoid mitochondria with prominent tubular cristae on electron microscopy. They were arranged in a sheet around small vessels, as a result of which the biopsy diagnosis of oncocytoma was changed to oncocytic glomus tumor. To our knowledge, this is the first report of an oncocytic glomus tumor arising from the trachea.

8/14. glomus tumor of the trachea. Report of a case with ultrastructural observation.

    Extracutaneous glomus tumors are unusual and their occurrence in the trachea has been recognized with extreme rarity. We present a case of surgically resected glomus tumor of the trachea in a 54-year-old woman who was initially misdiagnosed as having bronchial asthma because of expiratory wheezing. The tumor, located 7 cm below the vocal cord and 5 cm above the carina, was an intraluminally protruding polypoid mass that measured 1.5 X 1.2 cm and arose from the posterior wall of the trachea with a broad base. Microscopically, the tumor was predominantly of the solid type, but a small proportion of a glomangiomatous component was admixed. Ultrastructural study confirmed the presence of myofibrillar bundles with focal densities and fine pinocytotic vesicles along the plasma membrane. A structure similar to a nonneoplastic glomus was demonstrated in the submucosal layer of the posterior wall away from the tumor margin. This suggests that the tracheal glomus tumor occurs more often in the posterior wall where neuromuscular complex structures may develop more readily.

9/14. glomus tumor of the trachea. Immunohistochemical and electron microscopic studies.

    glomus tumor of the trachea which developed in a 51-year-old man was reported. He experienced frequent episodes of respiratory infections and hemoptosis for 9 months. Bronchofiberscopic study demonstrated a polypoid tumor in the upper trachea. Local resection of the tumor was performed and it arised from the membranous portion of the third and fourth tracheal rings. Histologically, the tumor was composed of medium-sized rounded cells, resembling carcinoid tumor. desmin and myosin immunoreactivities were found in most of the tumor cells. Electron microscopic examination showed that the tumor cells contained fine filaments with focal density, numerous pinocytotic vesicles along the plasma membrane and abundant mitochondria. The patient is well without evidences of tumor recurrence 2 years after the resection. This is the fourth report of the tracheal glomus tumor with definitive evidences of smooth muscle differentiation of the tumor cells.

10/14. Glomangioma of the trachea.

    A case of a glomus tumor arising in an unusual site, the trachea, is described. The tumor was composed of a mixture of glomus cells and mast cells. At the ultrastructural level, the glomus cells exhibited features of modified smooth-muscle cells.
