Summary
A large, malignant pancreatic Vipoma with liver metastases was successfully resected in a 55-year-old woman. Radical surgery is recommended for extensive metastatic islet cell tumors.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Endocrinology
Background:
- Pancreatic neuroendocrine tumors (PNETs) are rare neoplasms with diverse clinical presentations.
- Vipomas, a subtype of PNETs, are often associated with severe secretory diarrhea due to vasoactive intestinal peptide (VIP) hypersecretion.
- Metastatic disease at diagnosis presents significant management challenges.
Observation:
- A 55-year-old female presented with intractable diarrhea, a key symptom of VIPoma.
- Imaging revealed an unusually large pancreatic islet cell tumor with extensive liver metastases.
- Histological analysis, including immunohistochemistry and proliferation index, confirmed a low-grade malignant Vipoma.
Findings:
- The patient underwent successful R0 resection of the primary tumor and liver metastases.
- The postoperative course was uneventful, with complete resolution of symptoms.
- Intraoperative ultrasound facilitated complete tumor removal.
Implications:
- This case supports a radical surgical approach for PNETs with extensive liver metastases.
- Complete tumor resection can lead to favorable outcomes even in advanced disease stages.
- Multidisciplinary management, including surgical expertise and advanced imaging, is crucial for optimizing patient care.
