Answer: Bile duct hamartoma
Histology: The biopsy has three features of note: 1) there are multiple lesions; 2) they contain bile; and 3) they are lined by a flattened epithelium.
Discussion: Bile duct hamartomas (von Myenberg complexes) are potential mimickers of metastatic adenocarcinoma. They have the three features seen in this case: 1) there are multiple lesions; 2) they contain bile; and 3) they are lined by a flattened epithelium.
Bile duct adenomas are usually solitary and they do not contain bile. Pleomorphism and an invasive growth pattern help distinguish adenocarcinomas from bile duct adenomas and hamartomas.
