A Unique Case of Low-Grade Mucinous Neoplasm in Stump Appendectomy

Abstract

Background. We describe a case of a young male with a history of appendectomy one year ago, who developed symptoms of stump appendicitis, and after removing this stump, histopathology showed low grade neoplasm. Summary. Stump appendicitis is an uncommon complication after appendectomy and may lead to serious complications. Management of low-grade appendiceal mucinous neoplasm (LAMN) is controversial, and we discuss the importance of the case. Conclusion. The case of young male post stump appendectomy with histopathology showing LAMN in the stump of the appendix, which to our knowledge, is the first in the medical literature and, discuss the stump appendicitis and incomplete appendectomy concerning malignancy, mucinous neoplasm, and adenocarcinoma.

An Incidental Finding of Low-Grade Appendiceal Mucinous Neoplasm in a Case of Borderline Brenner Tumor of the Ovary

“…This monitoring strategy aims to detect any potential tumor recurrence or PMP-related complications. The five-year survival rate for patients with localized LAMN remains high at approximately 95% [ 19 ]. Therefore, identification of LAMN and BT in their early stages is essential for improved patient outcomes.…”

A retroperitoneal cyst arising from an appendix fragment

“…There have been only six reported cases of appendiceal stump adenocarcinoma in the literature in which the patients largely presented with symptoms of appendicitis 6 . Only one case of LAMN from an appendiceal stump has been reported in the literature 7 …”
