Light micrograph of a section through tissue from the uterus,in a case of a choriocarcinoma. This is a malignant (cancerous) tumour of trophoblast cells of the placenta. Trophoblast cells form part of the chorion,the membrane that surrounds a developing embryo. The chorion connects to maternal tissue to form the placenta. Choriocarcinoma may occur when an embryo fails to develop,but the placental tissue continues to proliferate | |
