Histological Reconstruction of a Von Meyenburg's Complex on the Liver Surface

Summary

We report here a case with four black nodules on a smooth liver surface. The cystically dilated part of the intralobular bile duct of the microhamartoma contained bile pigments. Neither liver cysts nor cystic kidney were found. Spicular processes from the dilated bile duct were attached directly to the liver cell cords, seemingly to receive the secreted bile juice from the bile canaliculi. A convoluted tubular bile duct communicated with an interlobular terminal bile duct in the neighbouring portal triad. Thus, the so-called microhamartoma had not developed separately in the liver acini but had arisen in connection with both the liver cell cords and the terminal bile duct as part of the still functioning bile duct.
