The Extent of Resection and Survellience in Appendiceal Mucinous Neoplasm: A Case Report and Review of the Literature

Summer Hassan*, Primal Singh

Background and aims: Appendiceal Mucinous Neoplasms (AMNs) are an uncommon malignancy affecting the appendix. The observed incidence is less than 1% among all appendectomy patients, with most cases occurring in middle aged and elderly patients. Although it is commonly referred to as the mucocele of the appendix, this terminology is used to describe a distended, mucus filled appendix. It is an ambiguous term best used to convey an imaging appearance rather than a pathologic entity because appendiceal mucinous lesions' underlying biology and behavior are incredibly variable, ranging from benign to neoplastic. Previously, the differentiation between benign and neoplastic appendiceal mucoceles was challenging; however, ten years ago, the Peritoneal Surface Oncology Group International (PSOGI) resolved this issue by establishing a consensus classification. They classified it into non neoplastic appendiceal mucinous lesions and neoplastic appendiceal mucinous lesions. The first is mainly a simple mucocele, which is attributed to obstruction and distention of the appendix, caused by degenerative epithelial changes without any evidence of neoplasia or hyperplasia.
