Area of Science:

  • Endocrinology
  • Gastroenterology
  • Surgical Oncology

Background:

  • Zollinger-Ellison syndrome is characterized by severe peptic ulceration and gastric acid hypersecretion.
  • It is caused by gastrinomas, islet cell tumors that secrete excess gastrin.
  • Gastrinomas can occur in various locations, complicating diagnosis.

Observation:

  • Gastrinomas are typically found in the pancreas or duodenum.
  • Unusual locations include lymph nodes, ovaries, bones, and the liver.
  • The origin of gastrinomas in these ectopic sites can be difficult to determine.

Findings:

  • This report details a case of a primary gastrinoma originating within a lymph node.
  • The presence of a primary tumor in this location mimics metastatic disease.

Implications:

  • Accurate localization and characterization of gastrinomas are crucial for effective treatment.
  • This case underscores the importance of considering primary tumors in unusual locations.
  • Enhanced diagnostic strategies may be needed for rare gastrinoma presentations.
