Summary
Primary gastrinomas, rare tumors, can occur in lymph nodes. This case highlights a possible primary lymph node gastrinoma in the jejunal mesentery, successfully treated with surgery, leading to normal gastrin levels.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Endocrinology
Background:
- Gastrinomas are neuroendocrine tumors that secrete gastrin, often associated with Zollinger-Ellison syndrome.
- Primary gastrinomas are typically found in the pancreas or duodenum, but lymph node involvement is recognized.
Observation:
- A 56-year-old woman presented with a suspected primary gastrinoma located in the jejunal mesentery lymph nodes.
- This location is outside the commonly reported gastrinoma triangle.
Findings:
- Surgical excision of the jejunal lymph node tumor was performed.
- Post-operatively, the patient remains asymptomatic with normalized serum gastrin levels.
Implications:
- This case expands the known anatomical distribution of primary gastrinomas.
- Highlights the importance of considering extranodal primary sites for gastrinomas.
- Suggests successful management of primary jejunal lymph node gastrinomas through surgical resection.
