Villous adenoma of the choledocho: an infrequent pathology of the main bile duct.

We present the case of a patient with obstructive jaundice due to a polylobulated lesion at the middle common bile duct that is identified as a villous adenoma of the main bile duct. This entity is infrequent with few references in the bibliography. It is a benign pathology but with risk of malignancy, so the diagnosis and resection is essential for adequate treatment.
