pseudomyxoma peritonei

A rare condition characterized by poorly-circumscribed gelatinous masses filled with malignant mucin-secreting cells; 45% of PPs arise from the ovary, usually in a mucinous cystadenocarcinoma; 30% are due to mucin-producing CA of the appendix Prognosis Mucinous ovarian cystadenocarcinomas of uncertain malignant potential–'borderline' tumors have a 10-yr survival of 95%; ovarian cystadenocarcinomas with pseudomyxoma have a 10-yr survival of 40%
