Case Discussion

Left hemicolectomy and appendectomy were performed and appendiceal mucocele and adenocarcinoma of left colon were proven.

Histology demonstrated non-invasive low grade appendiceal mucinous neoplasm and adenocarcinoma of the colon.

In patients with a mucocele, the risk of developing adenocarcinoma of the appendix is six times greater than that of the general population.
