title: [Primary pulmonary lymphoma presenting as an endobronchial polypoid tumor].
abstract: A 58-year-old woman because of coughing and an abnormality on a chest renggenogram was referred to our hospital. A chest X-ray film and a computed tomogram revealed atelectasis of the right lower lobe and a round tumor in the left lower lobe. Fiberoptic bronchoscopy revealed an endobronchial polypoid tumor in the intermediate bronchus, which completely obstructed the orifice of the right lower-lobe bronchus. Microscopical examination revealed B-cell diffuse, large, non-Hodgkin's lymphoma. No extrapulmonary lesion was found, and therefore primary pulmonary non-Hodgkin's lymphoma was diagnosed. Chemotherapy resulted in rapid and complete regression of the tumor, which was confirmed endoscopically and histologically. The patient was still in complete remission 8 months after the end of chemotherapy. There have been no additional interventions.
