[Sacrococcygeal teratoma in 2 fetuses at 5 and 6 months].

The two large mature sacro-coccygeal teratomas reported seem to be responsible for the death of fetuses in the fifth and sixth months of pregnancy. A review of the literature shows that teratomas are exceptionally rare during this period. Their outcome depends upon the degree of maturity of the tumor, its size, whether its location is pelvic or not, the presence of any associated malformations and upon prematurity.
