 A 54-year-old woman was admitted to our hospital with the chief complaint of bloody stool. Barium enema examination showed a circumferential and minimally elevated lesion, approximately 10 cm in length, in the rectum. It was covered with aggregated granular surface.

 Distensibility of the rectum was kept intact, as demonstrated by infusion of air. Endoscopic examination revealed a minimally elevated lesion involving an extensive area with the surface indistinguishable in color from the surrounding mucosa. The border of the tumor was clearly demarcated by dye spraying method. Examination of endoscopically obtained specimens revealed tubulovillous adenoma. Low anterior resection of the rectum was then performed.

 Macroscopically, the lesion was a slightly elevated tumor, measuring 10.5 cm in length. Histological examination revealed tubulovillous adenoma occupying most part of the tumor and adenocarcinoma in a very small area in the anal part of the tumor.
