Abstract: The optimal surgical management of Low-Grade Appendiceal Mucinous Neoplasm (LAMN) remains nuanced, requiring a balance between recurrence risk and operative morbidity. Although right hemicolectomy is frequently recommended, accumulating evidence suggests that simple appendectomy is adequate in well-defined circumstances. We report the case of a 52-year-old man with common cardiac comorbidities who presented with symptoms resembling acute appendicitis and was found to have a 10 cm LAMN. Given the intraoperative findings an intact appendix, a healthy appendiceal base, and absence of extra-appendiceal mucin simple appendectomy was performed with curative outcome. Using this case as an anchor, we provide a concise and practical synthesis of the key intraoperative and pathological criteria that can assist surgeons in confidently selecting appendectomy over hemicolectomy in appropriately selected patients. Our objective is to offer a clear, actionable framework for surgical decision-making in the management of LAMN.
