[Appendicular and ureteral adenomyomas. Problem of induction of the stroma in the endometriosis foci].

The authors discuss the contents and interpretation of the theories of pathogenicity of the condition of endometriosis after having defined it in its different forms and sites. Adenomyosis (internal endometriosis) and less than adenomyomata greater than (enternal endometriosis accompanied by smooth muscle hyperplasia) give rise to special problems of histogensis. The induction of fibro-muscular stroma into the area could be brought about by two different mechanisms. There is no need for ectopic endometrial glands to induce stroma in mulleriam organs. On the other hand non-mulleriam organs under the diaphragm seem to need that the glands are present and that they induce the surrounding stroma.
