[Vasoactive polypeptide-producing pancreatic carcinoma]

Area of Science:

• Endocrinology
• Oncology
• Gastroenterology

Background:

• Verner-Morrison syndrome is a rare condition characterized by severe diarrhea, hypokalemia, and gastric acid hypersecretion.
• It is typically caused by a neuroendocrine tumor, most commonly a VIP-oma (vasoactive intestinal peptide-producing tumor).

Observation:

• A 75-year-old male presented with symptoms consistent with Verner-Morrison syndrome.
• The underlying cause was identified as a pancreatic VIP-oma with an adenocarcinoma histological structure.

Findings:

• Treatment with the somatostatin analog octreotide provided symptomatic relief.
• Despite effective tumor management, the patient experienced a fatal outcome due to pulmonary embolism.

Implications:

• This case highlights the importance of early diagnosis and management of VIP-omas.
• It underscores the potential for severe complications, such as pulmonary embolism, even with effective symptomatic treatment.
• Pancreatic neuroendocrine tumors require a multidisciplinary approach for optimal patient outcomes.
