[Testicular feminization syndrome associated with acute hydramnios: apropos of 1 case]

We describe the first, to our knowledge, case of a feminizing testicle associated with acute polyhydramniosis observed at 21 weeks 3 days gestation. There was no fetal malformation or maternal disease that would explain the polyhydramnios. Prenatal diagnosis of feminizing testicle can now be made but is very difficult to suspect without similar family history or a suggestive ultrasonographic sign. Many fetal malformations have been directly linked to different causes of feminizing testicle, but for other malformations such as acute polyhydramnios, the pathogenesis remains unknown.
