Abstract excerpt
Primary duodenal adenocarcinoma accounts for less than 0.5% of all gastrointestinal cancers. We report a case of duodenal adenocarcinoma with highly divergent growth patterns consisting of poorly differentiated adenocarcinoma and neuroendocrine carcinoma proven to arise as a single neoplasm of monoclonal origin, as demonstrated by microdissection-based mutational profiling. Multicomponent growth patterns, as seen...
