title: Duodenal MALT lymphoma presenting with obstructive jaundice: report of a case and review of the literature.
abstract: BACKGROUND
  Mucosa-associated lymphoid tissue (MALT) lymphoma is a rare type of non-Hodgkin's lymphoma. The most common site for MALT lymphoma is the stomach.
  
  
  METHODS
  We are reporting a case of a 57-year-old man who presented with obstructive jaundice and was found to have duodenal MALT lymphoma. Unlike gastric MALT lymphoma which is responsive to Helicobacter pylori eradication therapy, duodenal MALT lymphoma does not have a definitive treatment.
  
  
  CONCLUSIONS
  To our knowledge, this is the first report of a duodenal MALT lymphoma presenting clinically as obstructive jaundice. We describe this case to alert physicians to consider this disease in the differential diagnosis of obstructive jaundice.
