Oat cell tumors in the common bile duct are extremely rare. We describe the case of a 76-year-old man with skin and mucous jaundice of 15 days' duration without constitutional syndrome. A tumor was diagnosed in the mid portion of the common bile duct. After surgical resection, pathological analysis revealed small-cell (oat cell) carcinoma. The treatment of these tumors is multidisciplinary. Surgery is followed by chemo- and radiotherapy.
