Dual malignancy: an interesting concurrent mixed epithelial ovarian tumor with esophageal carcinoma.

摘要

The occurrence of a second malignancy in a patient with a known malignant tumor is not very uncommon. Tumors of the ovary represent about 30% of all cancers of the female genital system, half of which are epithelial tumors. The reported incidence of mixed epithelial tumor (MET) varies from 0.5 to 4% of surface epithelial tumors. Although a few cases of ovarian MET have been reported in the literature, yet none could be found in association with a second malignancy in contrast to the present case.
