[Cytomorphometric diagnosis of dysplasias during dyshormonal and hyperplastic processes in the mammary gland].

A hundred and twenty-nine cytograms of benign tumors of the breast with different degrees of its dysplasia were morphometrically analyzed, by using a "MECOS-Ts" set for digital microscopy. The informative differentially diagnostic morphometric signs of nuclei were identified in mild, moderate, and severe epithelial dysplasias of the breast. The derived quantitative decision rules may reduce the error of a differential diagnosis of severe dysplasia by 2-3.5 times, as compared with a visual microscopy-based diagnosis.
