chorion epithelioma

A highly malignant tumour of the CHORION usually occurring after a HYDATIDIFORM MOLE has developed instead of a normal fetus. Bleeding may continue after an abortion or the cancer may develop months or years after the start of an unsuspected pregnancy. Multiple CORPUS LUTEUM cysts develop in the ovaries and the cancer spreads rapidly to all parts of the body. In one-fifth of cases the tumour develops following a normal pregnancy. The condition is treated with cancer chemotherapy.
