Synchronous primary cancers of the endometrium and ovary occur in approximately 10% of all women with ovarian cancer and 5% of all women with endometrial cancer. The pathogenesis of synchronous endometrial and ovarian cancer is unclear.
The synchronous tumors tend to be low grade and early stage. The prognosis is much better with survival approaching 10 years, than if their disease was chlassified as single organ disease with metastasis.
We report a case of unusual co-existence of endometroid adenocarcinoma of the contralateral ovary in 63-year-old woman. The patient recieved a surgical treatment and postoperative irradiation.
