[Pseudomyxoma peritonei. Two illustrative cases]
Abstract:
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.
Insights
Pseudomyxoma peritonei can develop from a ruptured appendix mucocele or ovarian tumor. This condition involves mucinous cells spreading on the peritoneum, often leading to poor prognosis and requiring repeated surgeries for intestinal obstruction.
Area of Science:
- Gastroenterology
- Gynecologic Oncology
- Abdominal Surgery
Background:
- Pseudomyxoma peritonei (PMP) is a rare condition characterized by mucinous ascites.
- It is often associated with mucinous tumors of the appendix or ovary.
Observation:
- Two cases of PMP are presented, originating from a ruptured appendix mucocele and a ruptured ovarian mucinous cystadenoma.
- These cases were observed between 1974 and 1981.
Findings:
- Generalized PMP develops when mucinous cells from a ruptured appendiceal mucocele or ovarian neoplasm (cystadenoma or cystadenocarcinoma) implant on the peritoneum.
- The mucinous material ('jelly') facilitates the spread and adhesion of these cells.
Implications:
- Rupture of mucinous tumors is the critical event leading to peritoneal dissemination.
- Recurrences are common, necessitating repeated surgeries for intestinal obstruction.
- The prognosis for pseudomyxoma peritonei remains poor despite ongoing treatments.
