"Choriocarcinoma is an aggressive, highly vascular tumour. When it is associated with gestation, it is often considered part of the spectrum of gestational trophoblastic disease; it is then termed gestational choriocarcinoma. When it occurs in the absence of preceding gestation, it is termed non-gestational choriocarcinoma (these occur most often in the ovary or testis)."
"Depends on the site of origin of the tumour. In females, it may occur during or outside of pregnancy; non-gestational choriocarcinoma of the ovary typically occurs in prepubertal girls and postmenopausal women. Testicular choriocarcinomas are usually present in male patients between ages 15 and 30 9."
