The radiological findings of cervical clear cell adenocarcinoma (CCA) have not been described previously. Here, we present MR findings of this neoplasm that included mixed solid and cystic components with eccentric solid components. These are similar to the MR features of ovarian CCA. Endometriosis was also noted in the uterine cervix. Coexistence of CCA and endometriosis at the cervix suggests that the pathogenesis may be similar to that of ovarian CCA.

In this study the human decidua, chorion and amnion were incubated for short term. Only the decidua, secreted much prolactin clearly among them as a function of time. When the amounts of prolactin in the maternal blood, cord blood obtained from umbilical vein, or those released into decidual incubation medium were compared with the amniotic fluid prolactin levels, only the decidual prolactin correlated significantly with the amniotic fluid prolactin. The urine obtained from newborns showed a low concentration of prolactin. These results suggest that the origin of prolactin present in the amniotic fluid is not from the mother or fetus, but from the decidua which has the ability of producing prolactin, and that prolactin secreted from this tissue may be transported into the amniotic fluid through the fetal membrane and accumulated there.

We report a rare case of endometrial carcinoma arisen from both horns of an asymmetrical double uterus.
