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%

One of the latter that should be highlighted is mucinous tumors of the appendix and ovary coexisting with pseudomyxoma peritonei. He had long felt that the appendix was the primary site of disease in these cases, provided evidence for it, and lived to see his theory accepted as correct by most authorities.
