Choriocarcinoma is a malignant, trophoblastic [1] cancerusually of the placenta. It is characterized by “early hematogenous spread” [ This quote needs a citation ] to the lungs. It belongs to the malignant end of the spectrum in gestational trophoblastic disease GTD.

It is also classified as a germ cell tumor and may arise in the testis or ovary. Choriocarcinoma of the placenta during pregnancy is preceded by:. Rarely, choriocarcinoma occurs in primary locations other than the placenta; very rarely, it occurs in testicles.

Although trophoblastic components are common components of mixed germ cell tumors, pure choriocarcinoma of the adult testis is rare. Pure choriocarcinoma of the testis represents the most aggressive pathologic variant of germ cell tumors in adults, characteristically with early hematogenous and lymphatic metastatic spread.

choriocqrcinome Because of early spread and inherent resistance to anticancer drugs, patients have poor prognosis. Elements of choriocarcinoma in a mixed testicular tumor have no prognostic importance. Choriocarcinomas can also occur in the ovaries.


Meaning of “placentaire” in the French dictionary

Characteristic feature is the identification of intimately related syncytiotrophoblasts and cytotrophoblasts without formation of definite placental type villi. Since choriocarcinomas include syncytiotrophoblasts beta-HCG producing cellsthey cause elevated blood choriocarcinnome of beta-human chorionic gonadotropin.

Syncytiotrophoblasts are large multi-nucleated placentqire with eosinophilic cytoplasm. They often surround the cytotrophoblasts, reminiscent of their normal anatomical relationship in chorionic villi.

Cytotrophoblasts are polyhedral, mononuclear cells with hyperchromatic nuclei and a clear or pale cytoplasm. Extensive hemorrhage is a common finding.

Since gestational choriocarcinoma which arises from a hydatidiform mole contains paternal DNA and thus paternal antigensit is exquisitely sensitive to chemotherapy. Coriocarcinome present, [ when? It may be required for those with severe infection and uncontrolled bleeding.

Choriocarcinoma arising in the testicle is rare, malignant and highly resistant to chemotherapy.

The same is true of choriocarcinoma arising in the ovary. Testicular choriocarcinoma has the worst prognosis of all germ-cell cancers. From Wikipedia, the free encyclopedia. Choriocarcinoma Micrograph of choriocarcinoma showing both of the components necessary for the diagnosis – cytotrophoblasts and syncytiotrophoblasts.


The syncytiotrophoblasts are multinucleated and have a dark staining cytoplasm. The cytotrophoblasts are mononuclear and have a pale staining cytoplasm.
