#283

Introduction: The existence of primary lymph node gastrinoma has been proposed but is controversial. We report two cases (Case A - 37-year-old male, Case B - 43-year-old male) of apparent primary lymph node gastrinoma.

Aim(s): We report two cases (Case A - 37-year-old male, Case B - 43-year-old male) of apparent primary lymph node gastrinoma.

Materials and methods: Case A had diarrhoea and abdominal pain. Localizing studies disclosed a solitary peripancreatic tumor. Case B presented with multiple duodenal ulcers. Biochemical confirmation of gastrinoma in both cases. Localizing studies indicated a solitary peripancreatic lesion. Proceeded to meticulous abdominal exploration including duodenal wall.
