| Abstract |
|
Neuroendocrine tumors (NET) of the major duodenal papilla are rare and the natural history of this disease is not clear. We experienced a case in a 31-year-old male. Duodenoscopy revealed an enlarged major duodenal papilla with central umbilication and nodularity. Endoscopic ultrasonography (EUS) demonstrated a 3-cm hypoechoic mass that was confined to the submucosa. A biopsy led to the diagnosis of a grade 1 NET. The patient refused surgery, so we performed an endoscopic papillectomy. The tumor was removed completely. The resected specimen confirmed the diagnosis of a well-differentiated NET and all resection margins were negative. Surgical resection is currently considered to be the gold standard for the treatment of a large NET of the major duodenal papilla; however, endoscopic resection is a possible treatment modality for patients at high surgical risk or who are reluctant to undergo surgery.
