[About morphology and classification of tumor-like and malignant prostatic lesions]

This review contains updated information on benign prostatic hyperplasia, basal cell hyperplasia, atypical adenomatous hyperplasia, prostatic intraepithelial neoplasia, different forms of carcinoma and rare prostatic neoplasms. The literature and the authors' clinico-morphological investigation of 687 patients are analysed. The diagnostic significance of some morphological markers (mitotic activity, the presence of crystalloids, amyloid bodies, the activity of endocrine-paracrine cells, etc) as well as the significance of PSA-test in various types of lesion are considered.
