A 66-year-old man was referred to our hospital due to a tumor at the liver hilum, with severe constriction of the upper bile duct. He underwent subtotal cholecystectomy for xanthogranulomatous cholecystitis at 2 years and 2 months before admission. Additional imaging studies and pathological diagnosis revealed that the tumor was malignant. We diagnosed residual gallbladder cancer with bile duct invasion. At laparotomy, the tumor had aggressively invaded the liver hilum, the hepatoduodenal ligament, and the duodenum. The residual gallbladder was resected. After operation, he received endoscopic metallic stenting for bile duct constriction, and systemic chemotherapy. Based on the pathological findings of the first resected gallbladder which did not show malignant lesions, it may be reasonable to say that the tumor developed in the residual gallbladder. Careful evaluation of the gallbladder is important for patients with suspected xanthogranulomatous cholecystitis who have undergone subtotal cholecystectomy.
