Low Grade Appendiceal Mucinous Neoplasm-A Rare Case Presentation

Abstract

The most common epithelial tumor affecting the cecal appendix is mucinous neoplasm. Malignant mucinous neoplasms of the appendix are rare entities, often asymptomatic. Low-Grade Appendiceal Mucinous Neoplasms (LAMN) are most often clinically silent. One of the rare causes of acute abdomen is appendiceal mucinous neoplasm, representing only 0.2-0.7% of all appendectomy specimens. These tumors are discovered incidentally either during a survey or at the time of surgery for other causes. Mucinous neoplasms of the appendix carry a complex diverse group of neoplasms ranging from simple mucoceles to complex pseudomyxoma peritonei. We present a rare case report of a 27 year old female, who was admitted to the surgical emergency with severe pain and tenderness in the right abdomen for 3 days. Emergency laparotomy with appendectomy was performed and based on the histopathological findings; a diagnosis of low grade appendiceal mucinous neoplasm (LAMN) was given. Our patient has recovered completely postoperatively and is well after 6 months of follow up period.
