[The nuclear morphotypes of epithelial cells in breast diseases]

Staining of the nucleolar ribosome organizer with AgNO3 followed by computer analysis of images by discriminant analysis helped distinguish 6 morphological types in the cells of cytological preparations of mammary glands. Comparison of the morphometrical data and results of visual examination of cells showed that the first type included nonproliferating fibroadenoma and mastopathy, type 2 fibroadenoma and mastopathy with moderate proliferation of epithelium, type 3 fibroadenoma and mastopathy with precancer epithelial proliferation, and types 4-6 included malignant proliferating cells which are compatible with well, moderately, and poorly differentiated cancer.
