Abstract

Biliary hamartomatosis (BH) occurs in 0.9% of children. Its origin is dysembriogenesis. Hamartomas of this disease show grey-white color, and can be located in subcapsular region or scattered at the parenchyma. Its size is usually less than 3 mm. Clinically, BH follows an asymptomatic course. The diagnosis of HBM initially requires an imaging test (ultrasound, CT or MRI). Histologically, each hamartoma has several groups of dilated intrahepatic bile ducts in a stroma that may be hyalinazed and/or calcified. BH do not require treatment, because its malignant potential is slow.
