Transduodenal resection of periampullary neuroendocrine tumor: A case report.

ABSTRACT:

Introduction and importance

Periampullary tumors are characterized as tumors that emerge nearby to the major papilla in the duodenum. They are rare lesions with an incidence rate of 0.4-0.48 per 100,000. Neuroendocrine tumors (NETs) constitute only 3% of all duodenal tumors. Their proximity to the major and minor papillae along with the gastric outlet raises a surgical challenge.

Case presentation

Our patient is a 40-year-old, male, medically free. He presented with history of a testicular mass. A CT scan of the abdomen and pelvis was done and showed a large retroperitoneal lymph node. A biopsy of the epididymal mass showed no evidence of malignancy. Excision of the left para-aortic mass revealed a metastatic lymph node of a well-differentiated neuroendocrine tumor. Further
