Dieulafoy's disease is the vascular anomaly characterized by the presence of arteries of persistent large caliber in the submucosa, and in some instances, the mucosa, typically with a small, overlying mucosal defect. Only a few cases of this lesion occuring in the bronchial system have been reported to date. The etiology of Dieulafoy's disease is still unclear, but chronic bronchial injury and/or congenital vascular malformation have been postulated. We encountered a case of bronchial Dieulafoy's disease that developed in a 69-year-old woman who had been treated for pulmonary tuberculosis for 4 months. Her chief complaint was hemoptysis and the bronchoscopic finding showed an intrabronchial protruding lesion produced by the arteries beneath the bronchial mucosa of the anterior segment of right upper lobe. She has been well after the surgical resection of right upper lobe.
