Goblet Cell Adenocarcinoma Associated with Appendiceal Diverticulum Presenting as Acute Appendicitis

Appendiceal diverticuli are strongly associated with appendiceal malignancy, and are usually only identified incidentally on histopathology or uncommonly present as acute appendiceal diverticulitis. Due to their rarity and mixed histological features, there has been significant inconsistency in the nomenclature and grading of goblet cell adenocarcinomas. This case report of a 30 year old female with incidental findings of both appendiceal diverticulum and goblet cell adenocarcinoma aims to reconcile established evidence as well as provide insight into the natural history of this uncommon appendiceal malignancy.
