We experienced a case of common bile duct granuloma with the infiltration of eosinophils. The patient was a 70-year-old man. He, who had taken hemodialysis, complained of general fatigue and itching. Laboratory studies showed liver dysfunction with hyperbilirubinemia. Abdominal US and CT showed gallstone only, but ERC showed elevated lesion of about 10mm in the common bile duct. And EUS showed solid tumor with hypoechoic area in that part. Histological findings of the biopsied specimens showed no malignancy but operation was performed since malignancy could not be ruled out. Pathological examination of the resected specimen revealed granuloma with the dense infiltration of eosiniphils.
