[Endometriosis of the uterine cervix. A hypothesis on its histogenesis].

Three cases of endometriosis of the cervix in association with the results of previous studies on the embryogenesis of the uterus made it possible during a morphological study for the authors to hypothesise that cervical endometriosis could develop in mullerian rests which persist in the stroma of the cervix. Menstrual blood incites the development, but degenerate menstrual fragments of endometrium do not implant to cause this development.
