A strategy of treatment of low-grade appendiceal mucinous neoplasm (LAMN) has not yet been established. We experienced 2 cases operated by laparoscopic surgery. The first case is 75 year-old-female, detected a cyst in the appendix by Computed tomography, and diagnosed as an appendix mucinous cyst. Laparoscopic appendectomy was carried out. Operation time was 45 minutes and the amount of bleeding were a little. The specimen was 8×4cm and mucinous liquid was collecting inside the cyst. The histopathological diagnosis was LAMN. Second case is 36 year old female, aware of the lower right abdominal tumor. Computed tomography showed cystic tumor in a point of an appendix, we diagnosed mucinous cyst of appendix.
