title: [Histological and molecular-biological markers of malignancy in different variants of thyroid papillary carcinoma].
abstract: Material for this study from 61 patients (thyroid papillary carcinoma) is shown to represent a heterogenic group of tumors differing from each other morphologically, molecular-biologically and histogenetically. The most malignant were long-cell and B-cell variants and the least malignant--a follicular variant. 81% of the tumors had neuro-endocrine differentiation and their malignant potential was higher compared to tumors without this differentiation.
