A 47-year-old man was admitted to our hospital for abrupt onset of hemoptysis and dyspnea. Chest roentgenography revealed a left lower mass shadow with obstruction of the left main bronchus. However, on the third hospital day, he expectorated a coagulum-like substance which resembled bronchial tree, and his symptoms then dramatically subsided. Except for small amounts of bleeding from left B10a, the endobronchus was intact on bronchoscopic examination, and the pathologic diagnosis of the tumor using resected material was fibrous histiocytoma of low-grade malignancy. In addition, given the similarity in histologic findings between the expectorated substance and resected tumor, the expectorated substance was considered to be a part of the tumor which had grown along the endobronchial tree.
