Summary

A rare pancreatic gastrinoma caused recurrent pancreatitis by blocking the main pancreatic duct. This unusual case highlights a gastrinoma presentation without typical peptic ulcer disease symptoms.

Area of Science:

  • Gastroenterology
  • Endocrinology
  • Oncology

Background:

  • Gastrinomas, neuroendocrine tumors secreting gastrin, are typically associated with Zollinger-Ellison syndrome and peptic ulcer disease.
  • Pancreatic gastrinomas are rare, and their presentation can be varied.

Observation:

  • A patient presented with recurrent clinical pancreatitis.
  • The pancreatitis was caused by a complete obstruction of the main pancreatic duct.
  • The patient lacked the classic signs and symptoms of peptic ulcer disease.

Findings:

  • The obstruction and recurrent pancreatitis were attributed to a pancreatic gastrinoma.
  • This case demonstrates an atypical presentation of a gastrinoma, emphasizing pancreatic duct obstruction as a primary manifestation.

Implications:

  • Highlights the importance of considering gastrinomas in the differential diagnosis of unexplained pancreatitis, even in the absence of peptic ulcer disease.
  • Suggests that pancreatic neuroendocrine tumors can present with diverse clinical syndromes beyond hormonal hypersecretion effects.
  • Underscores the need for thorough investigation of pancreatic lesions causing biliary or ductal obstruction.
