[Pleomorphic adenoma of the trachea].

A case report of a 43 year-old man with an extremely rare pleomorphic adenoma arising from the trachea is presented. Management was successful by bronchoscopic laser resection, which is a relatively harmless procedure compared to open tracheotomy. Tracheal tumors are often overlooked as a cause of pulmonary symptoms, until they give airway obstruction. This case was initially misdiagnosed as asthma.
