A 60-year-old asthmatic woman was admitted to our department because of bloody sputum and pneumonia. She had been treated with inhaled becromethasone dipropionate (800 micrograms/day) on an outpatient basis for 3 years. Fiberoptic bronchoscopy revealed polypoid lesions in the trachea, most of which were removed with forceps during the procedure. Numerous lymphocytes were observed in the biopsy specimen. Because immunohistochemical staining denied a monoclonal origin for the accumulated lymphocytes, the lesion was diagnosed as an inflammatory polyp. The patient was treated successfully with antibiotics for her pneumonia, and on a follow-up bronchoscopy 6 months later, only a small remnant of the lesion was noted. This is the fourth report about inflammatory polyps in asthmatics. In the previous 3 cases, however, marked eosinophil infiltration was consistently reported. The lymphocyte predominance in the present case therefore suggests a distinct etiology rather than asthmatic airway inflammation.
