Nephroblastoma (also known as Wilms’ tumor) mainly occurs in the kidneys of children. Nephroblastoma outside the kidneys may be observed in three situations: primary disease, metastatic disease and nephroblastoma arising in teratoma. Teratoma with nephroblastoma (TWN) of the adult ovary is a rare tumor and only one case has been reported. We report an unusual adult case of ovarian TWN presented to us with acute abdomen due to the spontaneous rupture of the ovary. The rupture occurred at the site of TWN, while contralateral ovary with only mature cystic teratoma component had no rupture. After one and a half months of the ovary sparing surgery, the tumor disseminated to the splenic hilum and the omentum. A complete staging with maximum cytoreduction followed by adjuvant chemotherapy were performed. She remains disease free until present.
