ABSTRACT
A 73-year-old woman with hemoptysis visited our hospital. Chest radiography showed a massive shadow on the right middle lung field. Bronchofiberscopic examination demonstrated a polypoid tumor obstructing the right middle lobe bronchus. A chest CT scan showed that the tumor was situated in the right middle lobe, obstructing the right pulmonary artery trunk. Sarcoma was diagnosed after a CT-guided biopsy. The tumor grew rapidly, giving rise to brain metastasis, which led to the death of the patient. An autopsy examination confirmed the diagnosis as pulmonary leiomyosarcoma.
