[Intra-hepatic biliary cystadenocarcinoma].
Biliary cystadenocarcinoma is a rare tumor of the intrahepatic biliary tract, which frequently develops in a preexisting benign biliary cystadenoma. In the present case, diagnosis was difficult because of the lack of specificity of clinical, biological and radiological findings. The correct diagnosis was only achieved by histological examination of the resected lesion. Macroscopically, the right lobe of the liver showed evidence of a whitish, multilolobed, malignant mass of about 6 cm in diameter. Upon light microscopic analysis, cysts were found to be lined with papillary forms. In some areas, epithelial cells were clearly malignant contrasting with persistent non dysplasic areas, suggesting the presence of underlying cystadenomas. Eleven months after complete surgical resection, the patient is in good condition with no evidence of recurrence.
