Fryns syndrome and erupted teeth in a 24-weeks-old fetus.

We describe a 24-weeks-old fetus with Fryns' syndrome (FS) and two erupted incisors. The present observations is another example of prenatal diagnosis of FS, based on ultrasonographically detected hernia diaphragmatica and cystic hygroma. It also adds an hitherto non described finding in FS. The presence of prenatally erupted teeth without any similar family history is discussed.
