Core Tip
Core Tip: Complete appendiceal intussusception (CAI) and appendiceal mucinous adenocarcinoma (AMA) is an extremely rare condition, which has not been reported in PubMed, and the preoperative diagnosis of this disease lacks specificity and is very easy to misdiagnose. This article summaries the clinical experience and lessons learned for the diagnosis and management of this disease. The main contributions include: (1) Novelty or clinical significance: First reported case of CAI and AMA in PubMed; (2) Educational value, providing insight into the diagnostic pitfalls and surgical decisions of CAI and AMA; and (3) A definite preoperative diagnosis can avoid secondary surgery.
