 An 80-year-old female visited our hospital to undergo colonoscopy as a further examination of positive fecal occult blood test. Colonoscopy revealed a sessile protruded lesion with a superficial slightly elevated lesion(0-Is+IIa, with a diameter of 30mm×22mm)in the lower rectum. The 0-Is part was nodule-aggregated lesion identified as a Hiroshima classification type C1/Sano classification type III A by the NBI(narrow band imaging)magnifying observation. This part showed a type VI pit pattern with low-grade irregularity based on a type IV pit by magnifying observation under indigocarmine. The 0-IIa part had a muskmelon-like unique surface pattern with few microvessels, and surface pattern did not match a conventional pit pattern, so we could not classify it except as a type VI pit pattern. We diagnosed it as an intramucosal adenocarcinoma with adenoma, and we performed an en bloc resection to include the 0-IIa part by Hybrid-ESD(endoscopic submucosal dissection).

 Histopathological examination revealed that both the 0-Is part and the 0-IIa part consisted of cells with various grade atypia which were intermingled irregularly. Thus, we diagnosed the cells as intramucosal papillary adenocarcinoma(pap>tub1). We speculated that the 0-IIa part which had a muskmelon-like unique surface pattern was the lesion that had extended laterally with replacing a surface layer around the 0-Is papillary adenocarcinoma.
