Abstract

A 67-year old woman with a history of long-term Chinese herb use was admitted to our institution complaining of abdominal pain. Barium enema disclosed rigidity of throughout the proximal colon and a slightly elevated lesion in the transverse colon. Colonoscopy showed diffuse and bronze mucosa in the proximal colon, which was compatible with mesenteric phlebosclerosis. There was also a reddish, elevated lesion in the transverse colon. Magnifying colonoscopy revealed irregular microsurface and microvessels on the surface of the lesion. Under a diagnosis of intramucosal cancer, the elevated lesion was treated by endoscopic submucosal dissection. Histological examination of the resected specimen showed intramucosal well-differentiated adenocarcinoma, and fibrous thickening of the vascular wall together with collagen deposition in the submucosa. The final diagnosis was an intramucosal cancer occurring in mesenteric phlebosclerosis.
