An epignathus is an extremely rare form of teratoma that arises from the or
al cavity, most commonly, from the palate. We describe a case identified so
nographically at 17 weeks' gestation after a raised maternal serum alpha-fe
toprotein was recorded. This pregnancy was terminated but we review the lit
erature over the last 10 years and describe the management options availabl
e in such cases.
