Primary Teratomatous Chorionepithelioma of the Ovary

Abstract

CHORIONEPITHELIOMA of the ovary may arise from two fundamental sources: a pregnancy, uterine or ectopic; and a teratoma. It is our purpose to discuss only the latter, and to add a case to the literature.Pick,¹ in 1904, described a nine-year-old girl whose abdomen revealed a teratoma of the ovary with mesodermal, entodermal and ectodermal components, and pure chorionepithelioma. Since then 12 other proved cases have been reported,^{2 3 4 5 6 7 8 9 10 11 12 13} only 3 of which are reviewed in the American literature.^{3 , 12 , 13} A few other cases must be eliminated because they followed pregnancies and may have represented metastases from uterine chorionepitheliomas that regressed spontaneously, . . .
