# Vanishing bile duct syndrome

- Lesion

In some diseases the small bile ducts inside the liver are destroyed and not replaced, so bile cannot leave.

Updated Nov 12, 2026

## Key points

- Definition on biopsy: loss of interlobular ducts in more than half of portal tracts (with an adequate sample).
- Each normal portal tract has a duct beside the hepatic artery branch: an artery without a duct is the clue.
- Causes: drugs (e.g. amoxicillin-clavulanate, some anticonvulsants), chronic allograft rejection, GVHD, PBC, PSC, sarcoidosis, Hodgkin lymphoma.
- Outcome depends on cause; drug-induced loss may recover if ducts regenerate.
- Keratin 7 or 19 stains help count remaining ducts.

## What it is

Vanishing bile duct syndrome is the loss of interlobular bile ducts in a large proportion of portal tracts (ductopenia), causing chronic cholestasis. It is the end result of different injuries: drug reactions, chronic rejection after liver transplantation, graft-versus-host disease, primary biliary cholangitis, primary sclerosing cholangitis, sarcoidosis, ischemia, Hodgkin lymphoma and some infections. The biopsy shows empty portal tracts with an artery but no accompanying duct.

## Structure

- Portal tracts with arteries but no bile ducts; little ductular reaction in some causes.
- Periportal cholate stasis and copper-associated protein; canalicular cholestasis.
- In chronic rejection: foam-cell arteriopathy of larger arteries.

## Step by step

- Immune, toxic or ischemic injury targets cholangiocytes of small ducts.
- Damaged ducts show irregular, vacuolated epithelium and lymphocytes.
- Ducts are destroyed faster than they regenerate.
- Bile flow fails: chronic cholestasis, pruritus, rising alkaline phosphatase.
- Persistent ductopenia leads to biliary fibrosis and sometimes cirrhosis.

## Markers

- Keratin 7
- Keratin 19
- Orcein (copper-associated protein)

## Memory aid

Count the pairs: every portal artery should have a duct partner; widowed arteries mean vanishing ducts.

## Test yourself

Think of the answer, then tap the question to see it.

## What biopsy finding defines vanishing bile duct syndrome?

Loss of interlobular bile ducts in most portal tracts, leaving hepatic artery branches without accompanying ducts.

## Which transplant-related conditions cause vanishing bile duct syndrome?

Chronic rejection of a liver allograft and graft-versus-host disease after bone marrow transplantation.

## Which immunostain helps count bile ducts?

Keratin 7 (or keratin 19), which marks biliary epithelium.
