Primary lymph node gastrinoma: A rare cause of abdominal pain in childhood

Gastrinoma is a hormone-secreting tumor associated with the Zollinger-Ellison syndrome. It is quite rare among children. The discovery of gastrinomas in unusual locations such as lymph nodes, bones, ovaries, and the liver poses a diagnostic dilemma as to whether the tumor is primary or metastatic. Here, we present a case of a primary gastrinoma within a lymph node. Copyright © 2013 by Lippincott Williams & Wilkins.
