We report a case of biliary adenofibroma in a 47-year-old woman, who presented with right upper quadrant pain for several months. Abdominal imaging revealed a 16-cm solid and cystic mass in the left hepatic lobe. Histologically, the tumor showed two distinct components: 1) cystic and tubular structures lined by low columnar to cuboidal biliary-type epithelium, and 2) a dense fibrous stroma composed of spindle-shaped cells with only mild nuclear pleomorphism and inconspicuous nucleoli. Mitoses and stromal invasion were absent. The glandular epithelium stained positively for keratin AE.3/Cam 5.2, cytokeratin 7, cytokeratin 19, carcinoembryonic antigen, and epithelial membrane antigen and had a low Ki-67 proliferative index. In addition, the epithelium was positive for D10 but did not stain for 1F6 or acid mucin with alcian blue stain. This staining pattern, similar to bile duct hamartoma (von Meyenburg complex) with which this tumor shares morphologic similarity, suggests that biliary adenofibroma originates from interlobular or larger bile ducts. Three years after a subtotal resection no metastasis or significant tumor growth was noted. However, given the marked nuclear p53 immunoreactivity and tetraploidy status observed in this tumor, we cannot exclude that biliary adenofibroma may represent a premalignant process that warrants complete resection and thorough histopathologic examination.
