[Von Meyenburg complexes - multiple biliary hamartomas mimicking metastatic liver lesions].

Von Meyenburg complexes are benign liver lesions usually consisting of dilated bile ducts surrounded by fibrous stroma. Their discovery is usually incidental and unsuspected during the early phase of the operative procedure. The sovereign diagnostic method is intraoperative frozen section examination. The complexes are not important as regards their clinical or functional significance. However, this uncommon entity should be taken into consideration in the framework of differential diagnosis of metastatic liver lesions.
