We experienced a case of cholesterosis of the common bile duct in which peroral cholangioscopy (POCS) was very useful for making a diagnosis. The patient was a 66‐year‐old man. He was admitted for examination of an asymptomatic mass in the pancreas. The mass was diagnosed as a serous cystic tumor of the pancreas. While examining the tumor, endoscopic retrograde cholangiopancreatography (ERCP) incidentally revealed a 7 mm irregular filling defect in the distal common bile duct. EST was then performed, followed by POCS, which revealed a clump of yellowish‐white Ip or Isp polyps in the distal bile duct. Histological examination of biopsy specimens taken under direct vision gave a diagnosis of cholesterol polyps containing foamy cells. POCS was useful for allowing direct observation of the characteristic color of cholesterol polyps, and for obtaining biopsy specimens under direct vision.
