Definition / general
Epidemiology
  • Uncommon
  • For primary disease, median age is 54 years
  • May be slight female predominance
Etiology
  • Origin of duodenal tumors appears distinct from nodal follicular lymphomas, but more similar to MALT lymphoma (Mod Pathol 2009;22:940)
Clinical features
Treatment
  • Treatment somewhat controversial since disease is rare and usually presents as low stage, but often multifocal (World J Gastroenterol 2010;16:5543)
  • Rituximab with chemotherapy (cyclophosphamide, vincristine and prednisone, possibly doxorubicin)
  • Also surgery, watchful waiting
  • Possibly antibiotics (Ann Oncol 2008;19:254)
  • Follow up with endoscopy (standard, capsule or double balloon)
