[Triploid embryonic molar pregnancy. Special aspects of one case (author's transl)].

Echotomography and a caryotype were carried out on the liquor and at an interval of one week between the two, two series of hormone levels were also carried out on the liquor and on the peripheral venous blood of a molar triploid pregnancy diagnosed clinically. These results have been compared with those that are known to occur in hydatidiform mole, and in other case histories that have been published of embryonic mole. The histological appearance of the fetal gonads resembles that found in Klinefelter's syndrome. The tests carried out on the HLA systems of the parents and of the fetus favours a maternal origin for the extra chromosomal complement.
