 A man in his 70s underwent colonoscopy owing to fresh bloody stool. A whitish lesion 20mm in size was observed in the transvers colon, following which he was admitted to our hospital. Magnifying endoscopy using blue laser imaging revealed that the whitish lesion had a round surface pattern and narrow vessel. Chromoendoscopy mainly revealed round pits, and serrated-like pits were partially found. Endoscopic resection was performed. Histology revealed sessile serrated adenoma/polyp with cytological dysplasia accompanied with xanthomatous change.
