Introduction: Mucinous appendiceal neoplasms are unique tumors in which >50 % of the tumor volume is composed of extracellular mucin. They may present as an unruptured mucin-filled appendix or, more commonly, with peritoneal metastases after rupture or transmural invasion of the primary tumor. This case report describes a case of presumed ovarian malignancy with final pathologic diagnosis of low grade appendiceal mucinous neoplasm.

Intraoperative findings revealed a periappendicular infiltrate from a perforated vermiform appendix of the tenia coli type.

Background: Neuroendocrine tumors (NETs) of the appendix are typically detected incidentally during appendectomy. Recent studies reported no metachronous metastases among patients with primary tumors <2 cm, regardless of lymph node status or referral for completion hemicolectomy. However, questions persist regarding the possibility of metastases developing decades after surgical resection, particularly because appendiceal NETs are frequently diagnosed in young adults and children.

Nevertheless, appropriate diagnosis is vital prior to surgery to prevent complications such as pseudomyxoma peritonei. This report details a case of a man in his 70s, who was admitted to the emergency department with right iliac fossa pain with imaging showing wall thickening of the caecum and the ascending colon.
