Pseudomyxoma peritonei (PMP) is characterized by mucinous ascites in the peritoneal cavity and might involve the omentum and peritoneum. The PMPs originating from the ovary are mostly caused by ruptured ovarian mature teratomas and mucinous ovarian carcinomas. The present case is a rare advanced mucinous borderline ovarian tumor and late recurrence in PMP in a 52-year-old menopaused woman. She presented with gradual abdominal enlargement and cystic abdominopelvic lesion with internal septa and ascites. The patient underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, infracolic omentectomy, lymphadenectomy, and appendectomy. Histopathologic examination revealed mucinous borderline tumors. About 5.5 years after the first surgery, she presented with abdominal bloating and a sonography report of peritoneal seeding in the abdomen and pelvis. Abdominal exploration showed gelatinous-mucinous ascites and disseminated peritoneal carcinomatosis. The final histopathologic evaluation indicated PMP. Although the recurrence of mucinous borderline tumors is in an average of two years, the present case had relapsed after 5.5 years as pseudomyxoma with borderline pathology.
