Mucinous cystadenocarcinoma
Unlike the more frequent benign mucinous cystadenoma, this malignant tumor sends invasive, mucin-secreting
cells through the appendiceal wall. In these photos note the tumor extending beyond the serosa and the
large amount of mucin production. Pseudomyxoma peritoneii is a term used when there is widespread
peritoneal involvement. Differentiation from primary ovarian tumor is sometimes difficult.
