Metastatic gestational choriocarcinoma: two cases.

Gestational choriocarcinoma is a rare, aggressive cancer of post-partum women. It metastasizes rapidly and can initially appear with involvement of the gastrointestinal, respiratory, genitourinary, or central nervous systems. Some reported cases show only metastatic foci with apparent spontaneous resolution of the primary site. We present two cases of gestational choriocarcinoma, showing some of these unusual presentations of a primarily gynecological problem.
