Background:
Pseudomyxoma peritonei is a rare condition consisting of mucinous ascites, most commonly arising from mucinous tumors of the appendix and occasionally from the ovary. Very rarely mucinous implants arise in the retroperitoneum without any intra-peritoneal involvement. This has been termed as pseudomyxoma extraperitonei.
Case Presentation:
We report a case of a 57 year old man who developed pseudomyxoma extraperitonei, 35 years after undergoing an appendicectomy for a perforated appendix.
Conclusions:
Pseudomyxoma extraperitonei has been previously reported, however we report the longest incubation period of 35 years for this condition.
Insights
Pseudomyxoma extraperitonei, a rare condition of mucinous implants outside the peritoneum, was observed after a 35-year incubation period following appendicectomy for a perforated appendix.
Area of Science:
- Gastroenterology
- Oncology
- Surgical Pathology
Background:
- Pseudomyxoma peritonei is a rare mucinous ascites condition, typically from appendiceal or ovarian tumors.
- Pseudomyxoma extraperitonei is an extremely rare variant with retroperitoneal mucinous implants and no intraperitoneal involvement.
Purpose of the Study:
- To report a unique case of pseudomyxoma extraperitonei.
- To highlight the exceptionally long incubation period associated with this rare condition.
Main Methods:
- Case report of a 57-year-old male patient.
- Review of medical history including appendicectomy for a perforated appendix.
Main Results:
- The patient developed pseudomyxoma extraperitonei.
- The condition manifested 35 years after the initial appendicectomy.
Conclusions:
- Pseudomyxoma extraperitonei is a recognized, albeit rare, clinical entity.
- This case represents the longest documented incubation period of 35 years for pseudomyxoma extraperitonei.
