Appendiceal Mucinous Incidental Neoplasm a Rare Case Report and Literature Review

Abstract

Mucinous appendiceal tumors consist of mucinous adenocarcinoma, low-grade appendiceal mucinous neoplasm, and high-grade appendiceal mucinous neoplasm. The incidence of non-mucinous adenocarcinomas is reduced. The most recent edition of the World Health Organization classification and recent consensus guidelines will enable the consistent application of agreed nomenclature. Not only is precise diagnosis essential for effective patient management, but it also facilitates the comparison of results across centers and tumor registries. The most prevalent benign adenoma in the appendix is serrated. It is imperative to differentiate these conditions from low-grade appendiceal mucinous neoplasms, as the latter can also resemble harmless ailments. Adenocarcinomas of the goblet cells are a rare subtype of appendiceal neoplasm. While appendiceal neoplasms are uncommon, they are not entirely so, and even the most seasoned pathologists may find them difficult to diagnose. In addition, appendiceal neoplasia classification and terminology have been subjects of contention for decades. Nonmucinous appendiceal neoplasms are less prevalent than mucinous tumors, and their association with other appendiceal neoplasm subtypes remains uncertain. A literature review of appendiceal mucinous neoplasms identified during laparoscopic appendicectomies is presented here.
