[Luteoma of the mother as a possible cause of external female pseudohermaphroditism].

Maternal virilization association with the birth of a virilized female infant has been reported in gravidas with luteoma. We describe a similar case with ambiguous genitalia (type Prader III). The only pathological finding was an elevated postpartum maternal serum testosterone (4.11 ng/ml). Excluding all differential diagnosis we conclude, that the only possibility for the virilization of the newborn female was a luteoma.
