A 35-year-old woman with past history of pneumonia in the right lung field 5 years before was admitted to our hospital because of fever and cough. Chest radiographs showed a pulmonary tumor with atelectasis of the right lower lung. Chest CT also revealed a round clear-edged tumor at the right S6 with atelectasis of the right lower lung lobe. Bronchoscopic findings showed a yellowish endobronchial tumor in the right truncus intermedius, which proved to be leiomyosarcoma. We could not find any other malignant lesion, and therefore, on a diagnosis of primary pulmonary leiomyosarcoma, right middle and lower lobectomy was performed with lymph node excision. Retrospective examination of the chest radiographs revealed not only that the original region of the leiomyosarcoma seemed to be near the site of the earlier pneumonia, but also that the atelectasis-like findings 2 years before were similar to the findings on this admission. It was reported that, if an operation could not be performed at an early stage, the prognosis might be poor. In the follow-up of the abnormal chest radiographic findings, the clinic physician should observe the symptoms from the same viewpoint as hospital doctors. It is important to keep an active relationship between clinic and hospital. We might have reached our final diagnosis earlier if we had been more active in seeking an examination for abnormal chest radiographic findings, without attaching too much importance to the patient's age.
