The clinical and pathologic features of two patients with biliary cystadenocarcinoma were presented and the previous literatures were reviewed. Case 1 : A 52-year-old man complained of heart burn and weight loss. Abdominal ultrasound and CT offered suspicions of biliary cystadenocarcinoma of the left hepatic lobe. Left hepatic lobectomy was performed, but the tumor invaded to adjacent viscera. The resected tumor (26×21×5.5 cm) was multilocular cystadenocarcinoma with mucin production. He survived for one year and 8 months after surgery. Case 2: A 60-year-old man suffering from sudden-onset frost and high fever underwent left lateral segmentectomy of the liver with a diagnosis of cystadenocarcinoma defined by biopsy specimen in previous operation. The tumor (6.0×4.5×3.5 cm) was multilocular cyst with mucin-producing papillary adenocarcinoma. He died of recurrent cancer 2 years and one month after surgery. The histogenesis of cystadenocarcinoma is still unclear because of its rare disease. The presence of benign epithelium in our cases may support their origin from cystadenoma.
