The histogenesis of pelvic endometriosis can not be sufficiently accounted for by a single theory. Thus it may be necessary to presure plural theories for the explanation of their histogenesis. On collected 253 cases of endometriosis, some clinical and pathological studies were carried out and classified to adenomyosis (A) 37%, ovarian and pelvic endometriosis (O.P) 17%, and others (A+0.P) 45%. Age of the group O.P tended to be younger, as compared with other groups. Pathological study revealed that in group (A+0.p), the lesion in uterine wall was extensive and deep proliferation in many cases, and it was frequently more at least than group A. Especially, it is necessary to distinguish from each other two different cases which showed endometriosis in the ovary and pelvic peritoneum, that is, to distinguish them by the presence or absence of adenomyosis. In the case of group O.P complicated by A, it is thought highly probable that discrete dissemination may take place from the foci of adenomyosis. In the case of group O.P there may be sufficient room for the application of the Sampson's theory or metaplastic theories. In view of conspicuous trait in the age, however, the possibility of lymphogenous dissemination of endometriosis may be valuable.
