During the last 6 years, we experienced three resected cases of malignant cystic tumor of the liver. The first patient was a 78-year-old woman. Dilated bile ducts around a cystic tumor were seen in the lateral segment of the liver. The tumor apparently communicated with the B3 bile duct and it was diagnosed as mucin-producing intrahepatic bile duct cancer. Histologically, the tumor invaded the capsule and the surrounding liver parenchyma. The second patient was a 68-year-old man with a multilocular lesion with papillary projection in the segment 4 and 8. Papillary and tubular adenoma cells as well as cancer cells were seen. The lesion was considered to arise from the adenoma. The third patient was a 48-year-old woman with a globular shaped multilocular tumor with papillary projections inside the segment 4. A communication between the tumor and the bile duct was observed. Neither small bile duct around the tumor nor superficial spreading of the tumor into the bile duct was seen. It was considered to arise within the simple cyst. The first patient died of the tumor 25 months after the operation. The second and third patients are alive 56 months and 16 months after the operation, respectively.
