Full Definition
Pseudomyxoma peritonei (PMP) is a rare clinical syndrome characterized by the accumulation of mucinous material within the peritoneal cavity, accompanied by mucinous tumor implants on peritoneal surfaces. While historically associated with ovarian mucinous tumors, most cases are now recognized as originating from appendiceal neoplasms with secondary ovarian involvement. The condition presents with progressive abdominal distension due to mucinous ascites and requires specialized surgical management.
Usage
Usage note: Most cases are of appendiceal, not ovarian, origin.
