Introduction:Appendiceal mucocele is a rare condition which was described as an obstructive dilatation of the appendix caused by intraluminal accumulation of mucoid material.

Case Reports: We present a case of 26 years old male who came for elective appendectomy which intraoperatively found to have  mucocele of appendix which was treated successfully by appendicectomy. The second case was a 55 years female who presented with a right iliac fossa mass with mesenteric lymph nodes enlargement ,underwent right hemicolectomy and the histopathological report showed mucinous cystadenoma of the appendix.

Conclusion: In conclusion, appendiceal mucocele is a rare disease and has a clinical presentation that resembles acute appendicitis or RIF Tumour.
