Description

A case of laparoscopically resected mucinous cystadenocarcinoma of the appendix is reported, together with some bibliographical comments.<br> A 57-year-old woman was seen at the hospital because of right lower abdominal pain lasting for several months. Barium enema study revealed a tumor with smooth margin in the cecum. Colonoscopic fiber visualized submucosal elevated lesion with smooth surface in the cecum. Abdominal CT scan and an ultrasonography revealed an 80×25mm luminal structure running up and down along the dorsum from the ileocecal region to ascending colon. From these findings, benign mucinous cyst of the appendix was diagnosed and a laparoscopic partial cecectomy was performed. On a histopathological study, mucinous cystadenoma ofthe appendix was diagnosed. No malignant findings were revealed and surgical stumps were negative. Postoperative course was uneventful and the patient was discharged from the hospital on the 14th hospital day.<br> Laparoscopic surgery appears to be the first choice for the disease except clearly malignant cases, however, sufficient preoperative diagnosis and informed consent considering a malignant potential are important.
