Is Mucocele of the appendix cancerous?
There is a range of benign to malignant conditions that can occur in the appendix to form a mucocele. Two of these conditions are mucinous cystadenomas and mucinous cystadenocarcinomas.

How rare is Mucocele of the appendix?

What is the incidence of mucocele in the US?
The incidence of mucocele has been reported to be 0.1 to 0.5 per cent in surgically removed appendices.
