Also known as von Meyenburg
complexes, bile duct hamartomas arise from ductal plate malformations that involve the small interlobular bile ducts.
Konrad von Meyenburg of Geneva, Switzerland, who received Swiss patent no.
Von Meyenburg described his new invention this way: "The power of earth cutting by edge tools depending mainly upon the sharpness, section and surface of the tools and their free cutting, I make them of small section and surface, preferably self-sharpening, elastic and independent; so that each edge, also rotated mainly in a circle, may give way laterally and backwardly, like the claws of a scraping animal, and follow the way of least resistance upon a trembling or shivery curve.

The vineyards on the Lake of Zurich are small but at least one, Kaspar von Meyenburg

This leads to different congenital bile duct disorders, such as Caroli disease and syndrome, autosomal recessive polycystic kidney disease, autosomal dominant polycystic kidney disease, congenital hepatic fibrosis, and bile duct hamartomas (BDHs, also known as von Meyenburg complexes).
However, multiple BDHs (also known as von Meyenburg complexes) were found in the vicinity of the cholangiocarcinoma, leading to speculation that they were related to its pathogenesis.
