Abstract
A case of primary racemose hemangioma of the bronchial artery is reported. A 52 year-old woman was admitted because of repeated massive hemoptysis. Bronchoscopic examination revealed an aneurysm with irregularity of the wall of the right basal bronchus, but the nature and location of the couse of hemoptysis was not detected by bronchoscopy or bronchography performed previously at another hospital. Hemoptysis was considered to be due to racemose hemangioma, which was confirmed by extraordinal hypervascular area on bronchial arteriogram and hemangiomatous hyperplasia of submucous vessels, on resected specimen of right basal bronchus. And also the lesion was considered to be primary racemose hemangioma of the bronchial artery, because there were no findings of chronic inflammatory lesions in the histological examination. Bronchoscopy is the most valuable examination for detecting the location and nature of hemoptysis, and bronchial arteriography seems to be another reliable technique for identifying the area and origin of hemoptysis.
