Core Tip

Core tip: Enteropancreatic endocrine neoplasms affect up to 90% of multiple endocrine neoplasia type1 (MEN1) patients. Gastrinomas are the most common functional enteropancreatic neuroendocrine tumors and were thought to be located almost exclusively in the duodenum in MEN1 patients. This study describes our experience regarding ectopic biliary tree gastrinomas in MEN1 syndrome. Our data doubles the number of cases reported in literature on this topic. Furthermore, the present study brings to light important issues that could help to establish the best biochemical and oncological cure for such cases, of which clinicians should be aware to improve the management of MEN1 patients.
