title: Primary hemangiopericytoma of the trachea.
abstract: A 28-year-old man arrived at our hospital complaining of severe dyspnea. Bronchoscopic findings demonstrated that a tumor was located approximately 4 cm distant from the vocal cord, occupying most of the tracheal lumen. To urgently relieve the dyspnea, some parts of the tumor were cauterized with the neodymium:yttrium-aluminum garnet laser. Histopathologic examination of the cauterized specimen revealed malignant hemangiopericytoma. During the operation, the tumor was resected en bloc with a tracheal segment containing four tracheal cartilages. The patient's postoperative course was uneventful with no evidence of recurrence 1 year after the operation.
