The Longest Adult Appendix Recorded: A 38-cm Mega-Appendix Presenting with Peri-Appendiceal Phlegmon Mimicking Acute Appendicitis: a case report
This case report documents the longest recorded adult appendix at 38 cm, which presented with severe peri-appendiceal inflammation and a phlegmon mimicking acute appendicitis despite having a histologically normal mucosa, suggesting that extreme length can trigger extra-luminal necrosis and abscess formation independent of intrinsic luminal disease.
