title: [A case of early cystic duct carcinoma concomitant with xanthogranulomatous cholecystitis (XGC)].
abstract: We reported a case of early cystic duct carcinoma concomitant with xanthogranulomatous cholecystitis (XGC). This case was a 72-year-old man in whom thickening of the gallbladder wall was pointed out an abdominal ultrasonography and elevation of the CA19-9 level was detected at a local clinic. Endoscopic ultrasonography and CT demonstrated a mass in the cystic duct. Mapping biopsy using peroral cholangioscopy (POCS) revealed a diagnosis of cystic carcinoma with superficial flat growth, therefore a pylorus-preserving pancreatoduodenectomy was performed. Histopathological diagnosis was well differentiated papillotubular adenocarcinoma with superficial flat spread and the thickening of the gallbladder wall was XGC. A case of early cystic duct carcinoma concomitant with XGC is extremely rare.
