Clinical case of a giant asymptomatic low-grade appendiceal mucinous neoplasm

Introduction: Low-grade appendiceal mucinous neoplasms (LAMNs) are rare tumors with nonspecific clinical features. Abdominal computed tomography (CT) is the primary diagnostic tool. Surgical resection is the standard treatment, requiring “en bloc” tumor removal to minimize the risk of rupture. Laparoscopic surgery is a safe and effective approach. Case Report: A 74-year-old female patient was admitted for evaluation of a pelvic mass. Physical examination revealed a non-tender abdomen with a palpable pelvic mass. Imaging showed significant thickening and dilation of the appendix. Laparoscopic surgery confirmed LAMN. The patient recovered well with no complications at follow-up. Conclusion: Low-grade appendiceal mucinous neoplasms are rare tumors with variable presentations. Abdominal CT and enteroscopy are crucial for diagnosis. Laparoscopic surgery offers a safe and effective treatment, ensuring favourable outcomes.
