title: [Theca-like reactions in the stroma of cilioepithelial ovarian neoplasms].
abstract: The work deals with the study of the so-called theca-like reaction in the stroma of 283 cilioepithelial tumours of the ovary (50 simple, 28 proliferating cystadenomas, and 205 cancers developed from cilioepithelial cystadenomas). The composition of the interstitial tissue of neoplasms of this type (except simple cystadenomas) included cells morphologically undistinguished from the thecal elements of the ovary. They may contain cholesterolethers and sets of redox enzymes typical of the steroidproducing tissues. Manifestation of the theca-like reaction (findings of morphometry) depended upon the degree of anaplasia of the tumour epithelium: it was most pronounced in malignant highly differentiated tumours, and least pronounced in drastically anaplasic cancer.
