Core Tip

Core tip: Appendiceal mucinous neoplasms (AMNs) are rare tumors. Only a few cases have been reported and most patients have no typical clinical manifestations. As such, diagnosis and treatment are a clinical challenge; even the terminology of AMN grading and staging has been controversial and is not standardized yet. Malignant AMNs have a poor curative effect and no treatment standard has been established. Here, we report a female patient with AMN who has survived throughout follow-up, now at 1 year post-surgery. A review of the latest literature is also provided to improve the overall awareness and understanding of this disease.
