Abstract

We describe a 42-year-old man who presented with painless obstructive jaundice, organomegaly and lymphadenopathy. Biopsy of the ampulla of Vater revealed the presence of increased populations of plasma cells which stained positively for immunoglobulin G4. He was treated with prednisolone and demonstrated significant clinical improvement 1 month later. A further case is described and a review of the literature is also provided.
