The Molecular Pathology of Appendiceal Neoplasms

Abstract

Abstract We review the molecular pathological changes of appendiceal neoplasms, in part using the consensus terminology agreed by the Peritoneal Surface Oncology Group International (Am J Surg Pathol 2016;40(1):14–26; Histopathology 2017;71(6):847–858), with appendiceal neoplasms subcategorized as hyperplastic polyps and serrated lesions (with and without dysplasia), appendiceal mucinous neoplasms (low and high grade), adenocarcinoma, goblet cell tumors, and neuroendocrine neoplasms.
