[Rhombencephalic tissue in an ovarian teratoma with cerebellar foliation and maturation of the postnatal type].
In a women 32 years old, primipara with pregnancy to term hesitated caesarian birth, a cystic mature teratoma was found on both ovaries. While the content of the cyst of the left ovary appeared deprived of descriptive interest, in that of the right ovary, beyond to locks of hair, tegumental tissue, sebaceous matter and to a bone in miniature, they were structures relatively well diversified belonging to the nervous central system and particularly to the rhombencephalus (hindbrain). At the microscopic examination it was well recognizable a cerebellar structure with a microfolic configuration and with histological maturity of the postnatal type, identified for her neuronal depletion of the layer of the external granules and for the advanced myelination. It is advanced the hypothesis of a correlation between the maturation of the teratoma and the coexisting term pregnancy.
