Two Cases of Glomus Tumor Arising in Large Airway: Well Organized Radiologic, Macroscopic and Microscopic Findings
A 64-year old man, who had no clinical respiratory symptom and previous medical problem except hypertension, visited our hospital due to incidentally found tracheal mass on the examination of health care program using computed tomography (CT). CT revealed a highly enhanced 2.6 cm-sized, iceberg shaped mid-tracheal tumor involving the right-side posterolateral wall, suggesting the impression of tracheal paraganglioma (most likely), sclerosing hemangioma and leiomyoma (). On the bronchoscopic examination, a 1 cm-sized, vascular mass was noted 7 cm below the vocal cord (). However, pulmonary function test (PFT) showed no abnormal findings: forced vital capacity (FVC), 3.6 L; forced expiratory volume in 1 second (FEV1), 3.13 L; and FEV1/FVC, 87%. Tracheal resection and anastomosis was done. He is well without evidence of local recurrence or complication two years after operation.
