Prenatal transvaginal diagnosis of the ectrodactyly, ectodermal dysplasia, cleft palate (EEC) syndrome.

Transvaginal ultrasonography performed at 14 weeks' gestation demonstrated a bilateral cleft lip and lobster-claw deformities of the hands and feet, in keeping with the diagnosis of EEC syndrome (ectrodactyly or lobster-claw deformity, ectodermal dysplasia, and cleft lip and palate). The fetus was aborted and the diagnosis of EEC syndrome was confirmed.
