Von Meyenburg Complex in a Cat and a Dog, and Mini Literature Review

Biopsies of liver from a 10-year-one-month-old male, neutered dog and an adult, male, domestic short haired cat of unknown age were received and microscopically examined. In both cases ectatic bile ducts consistent with von Meyenburg complex also known as bile duct hamartoma (BDH) was diagnosed. The epithelium reacted positive for E-cadherin and CK7 by immunohistochemistry (IHC). Bile duct hamartoma is rare in dogs and cats. BDH is reported to be due to failure of involution of embryological remnant during embryogenesis. The current brief report describes cases of bile duct hamartoma in an adult dog and a cat and would contribute to the literature on BDH in felines and canines.
