ABSTRACT

Appendiceal mucinous neoplasm (AMN) includes a group of diseases which are classified into Low grade and high grade appendiceal mucinous neoplasm (LAMN and HAMN) respectively. These rare tumors have limited published data and more trials are required to grasp a better understanding of the disease. In this report, we discuss a rare case of HAMN in a 54-year-old Nepalese male presenting to our hospital complaining of right lower abdominal pain for 7 days associated with Nausea, vomiting and anorexia. On examination abdomen was soft, mildly distended with severe right iliac fossa tenderness and positive rebound tenderness. A presumptive diagnosis of complicated appendicitis was made. However, the final diagnosis of HAMN was made after the pathological specimen was resected surgically by laparoscopic appendectomy and was sent for histopathology. Our case report highlights the importance of including HAMN as a differential for complicated appendicitis cases especially in patients at their 60 decades.
