Neuroendocrine tumors are uncommon, including VIPoma that produces vasoactive intestinal polypeptide. We report a 45-year-old female presenting with a history of diarrhea lasting three months. An abdominal CAT scan showed a solid tumor in the body of the pancreas. A fine needle aspiration biopsy of the tumor was compatible with a neuroendocrine tumor. The patient was subjected to a partial pancreatectomy, excising a 4 cm diameter tumor. The pathological study was compatible with a neuroendocrine carcinoma. There was no regional lymph node involvement. During the postoperative period the results of serum vasoactive intestinal polypeptide were received. These were 815.9 pg/ml before surgery and normalized after the operation.
