Summary

A VIPoma, a rare neuroendocrine tumor, caused severe watery diarrhea and electrolyte imbalances in a patient. Treatment with a somatostatin analogue led to significant symptom improvement.

Area of Science:

  • Gastroenterology
  • Endocrinology
  • Oncology

Background:

  • Vasoactive intestinal polypeptide (VIP)omas are rare neuroendocrine tumors that can cause severe secretory diarrhea and hypokalemia.
  • Diagnosis often involves imaging and hormone level measurements, but can be challenging due to the rarity of the condition.

Observation:

  • A 53-year-old woman presented with prolonged watery diarrhea and hypokalemia.
  • Imaging revealed liver calcifications, pancreatic duct obstruction, and pancreatic calcification.
  • Elevated gastrointestinal hormone levels, including VIP, pancreatic polypeptide, and neurotensin, were detected.

Findings:

  • Immunohistochemical analysis confirmed a metastasizing VIPoma.
  • The patient's symptoms were significantly alleviated by the administration of the somatostatin analogue SMS 201-995.

Implications:

  • This case highlights the importance of considering VIPoma in patients with refractory secretory diarrhea and electrolyte disturbances.
  • Somatostatin analogues represent an effective therapeutic option for managing VIPoma symptoms.
  • Early diagnosis and treatment are crucial for improving patient outcomes in VIPoma cases.
