A Case of True Diverticulum of the Appendix with Low-grade Appendiceal Mucinous Neoplasm

Abstract

The patient was a 70-year-old woman who presented with pain in her right lower abdomen. She was diagnosed as having an appendiceal diverticulum with appendiceal mucinous neoplasm and underwent laparoscopic cecectomy. Based on the histopathological findings, we made the diagnosis of true diverticulum of the appendix complicated by low-grade appendiceal mucinous neoplasm (LAMN).

This is the first report of an appendiceal true diverticulum with LAMN. Herein, we report a rare case with a review of the literature.
