A 60-year-old male patient experienced fever, body chills and jaundice. He had a periampullary ulcerative lesion and underwent radical pancreaticoduodenectomy. Histopathologically, the tumor consisted of an LCNEC component and an adenocarcinoma component. Simultaneous LCNEC and adenocarcinoma has been reported in a few cases. Our patient had a coexisting LCNEC and an adenocarcinoma of the ampulla of Vater. We also present a review of the literature
