Description

We reported two cases of racemose hemangioma of the bronchial artery. Case 1 was a 59-year-old man with liver cirrhosis, who was admitted with bloody sputum. The chest roentgenogramrevealed a tumor shadow about 40mm in diameter in the right lower lung field. Bronchoscopic examination showed an endobronchial polyp at the right B2. We suspected this polyp was a submucosal tumor, and then we performed transbronchial biopsy. Immediately after the biopsy, massive bleeding occurred with repeated massive bloody discharge in spite of bronchoscopic hemostasis. Then we performed right pneumonectomy including lung cancer of the lower lobe. The second case was a 41-year-old man, who was admitted with hemoptysis. He had expectorated bloody sputum from his childhood. Submucosal dilated vessels were found at the right upper bronchus on bronchoscopic examination. Bronchial arteriography revealed three convoluted bronchial arteries connected to the right pulmonary artery through the right upper bronchus. He underwent right upper lobe lobectomy. Pathological examinations of the two cases demonstrated dilated and convoluted vessels around the bronchus, suggesting racemose hemangioma of the bronchial artery.
