[Digestive hemorrhage from a duodenal neuroendocrine tumor. Diagnostic-therapeutic features and emergency surgical strategy].

The Authors report a rare case of duodenal neoplasia in a 17 year old boy. The patient was admitted in an emergency setting for hemorrhagic shock and duodenal perforation. Laparotomy was performed and a huge perforated neoplasia of the duodenum was found. Conservative approach was preferred, since the intraoperative histology was unuseful in choosing the better procedure: thus just a tumorectomy and closure of the duodenum were performed. Pathology examination demonstrated a neuroendocrine primitive duodenal tumors not well differentiated and with high grade of malignancy. The Authors discuss the role of the elements, clinical features and pathology, as well as emergency and postoperative management.
