Predictability of trophoblast tumor outcome based on chromosome constitution

[Ovarian choriocarcinoma: about one case]

We report the case of a woman, 43 years old, presenting with an ovarian choriocarcinoma. This patient, addressed for a right-side suspicious pelvic mass, had an exploratory laparotomy. Frozen section found an ovarian cancer. The patient had total hysterectomy, left annexectomy and a complete staging surgery. Histology concluded to an ovarian gestational choriocarcinoma. It is a rare germinal tumour, the treatment of which was medical, with radical exeresis and complete staging surgery associated with polychemotherapy.

Pure nongestational choriocarcinoma of the ovary. Report of a case

The authors report a case of pure nongestational choriocarcinoma of the ovary (NGCO) in a prepubertal female patient and emphasize the electron microscopic and immunohistochemical findings. Pure NGCO accounts for 0.6% or less of all ovarian neoplasms. Distinction from gestational choriocarcinoma of the ovary (GCO) is important because of the worse prognosis of NGCO. No distinctive ultrastructural or immunohistochemical differences were found between NGCO and GCO. Cytogenetic studies may be indicated in future cases to investigate potential reasons for the difference in prognosis.
