Invasive recurrence of an intestinal-type mucinous epithelial neoplasm of low malignant potential: case report and review of the literature

Pseudomyxoma peritonei is only rarely seen in conjunction with primary ovarian tumors. It has been suggested that only ruptured mucinous tumors arising in ovarian mature cystic teratomas can result in this clinical picture. We describe a case of a late invasive recurrence of a mucinous intestinal-type borderline ovarian tumor arising from a mature teratoma after complete surgical debulking. Borderline ovarian tumors behave indolently in the overwhelming majority of cases, and the prognosis is therefore usually outstanding.
