[Pseudomyxoma peritonei. Two illustrative cases].

The authors present two cases of pseudomyxoma peritonei caused by a ruptured mucocele of the appendix and by ruptured mucinous cystadenoma of the ovary observed during the period from 1974 to 1981. It is demonstrated that the development of a generalized pseudomyxoma depends upon the rupture of mucocele or of mucinous cystadenoma or cystadenocarcinoma of the ovary with graft of the muciparous cells floating in the "jelly" on the peritoneum of neighbouring organs. Cause of recurrences which require repeated operations for intestinal obstruction, the prognosis is poor although other treatment is carried on post-operatively.
