Periampullary adenocarcinoid: diagnostic dilemma.
The growth in periampullary region needs proper evaluation as they can arise from duodenum, pancreas and extra hepatic biliary tree. We have reported a case of adenocarcinoid of duodenum presenting as periampullary growth with obstructive jaundice. Histologically, tumor displayed biphasic pattern, i.e. tubuloglandular architecture with admixed sheets of neuroendocrine cells without pancreas and extra hepatic biliary tree involvement. The adenocarcinoids are of great diagnostic challenges for the pathologist interpreting endoscopic biopsy for the frequent misinterpretation as negative due to their submucosal location or as adenocarcinomas due to tubulo-glandular architecture.
