ABSTRACT

Mucocel is a rare pathological lesion of appendix. It is characterized with cystic dilatation caused by mucus stasis in the appendiceal lumen. Usually they are asymptomatic. Generally diagnosis can be made during intraoperative observation or postoperatively histopathologicaly. We aimed to present a case that laparotomy had been performed in whom imaging techniques revealed a cystic mass over the right lower abdominal quadrant with smooth contours, and high carcinoembrionic antigen (CEA) levels suggesting right over malignancy. Right hemicolectomy was performed and postoperatively histopathological examination showed mucinous cystadenoma of the appendix.
