Mucocele of the appendix and colorectal neoplasms

Abstract

We present herein the case of a 64 year-old woman with a huge mucocele of the appendix coexistent with an adenomatous polyp 2 cm. in diameter in the transverse colon. From the reports of Ahmed, Wolf and Higa we know that mucoceles may coexist with colorectal neoplasm's. Though the polyp in the transverse colon was not malignant, it had a potential source of becoming malignant in the future. We consider that once the diagnosis of mucocele has been made, every patient has to be searched for the possible coexistence of colorectal neoplasm's and all polyps in the colon have to be removed because these patients are at greater risk for developing colorectal cancers.
