title: [Ultrastructure of the polysome-lamella complexes in ovarian cancers].
abstract: Electron-microscopy was used to study the intraoperative material in 37 patients with serous (24), mucinous (8) and endometroid (5) ovarian neoplasms of benign, boundary and malignant forms. It was shown that the polysome-lamellae complexes are characteristic only of the carcinoma epithelium and practically are observed neither in benign nor in boundary analogs. This may serve an additional criterion of a malignant nature of neoplasms at the ultrastructural level. Taking into account the architectonics 3 variants of the polysome-lamellae complexes should be distinguished: polysome-lamellae, lamellae and lattice structures. All these variants may be encountered in one and the same tumor.
