Abstract
A 82-year-old female was admitted to our hospital with hematochezia. A flat protrusion with redness was observed in the ascending colon by colonoscopy. Spurting bleeding occurred from this lesion after biopsy, and vascular disease was suggested. Selective angiography revealed as follows; 1) dilatation of the feeding arteries, 2) proliferation, tortuousness and aggregation of capillaries and 3) early venous return. Therefore, Vascular ectasia of the ascending colon was diagnosed. Twenty-six cases of Vascular ectasia of the colon have been reported in Japan. In most of these cases, the lesions were located in the right colon, which is different from adenoma. Therefore, it is suggested that a flat protrusion associated with moderate hemorrhage seen in the right colon could be Vascular ectasia.
