[X-ray morphologic characteristics of microcalcination in benign processes and cancer of the breast].

Mammographic and morphologic examination was carried out in 136 females bearing microcalcinates in breast tissue. Morphologic examination identified benign tumors (mostly fibrous cysts) in 72.1% and cancer (mostly ductal and lobular carcinoma in situ or initial signs of invasion) in 27.

[Small focal lesions of the breast: a clinico-morphological analysis].

Morphological and mammographic study of small (less than 1 cm) focal mammary gland lesions of 170 women revealed foci of typical epithelium proliferation of the ducts and lobules, fibrosing adenosis, small duct papillomas and fibroadenoma, intraductal and ductal carcinoma in situ, sometimes with small invasion foci, infiltrating carcinoma, infiltrating lobular carcinoma. Peculiarities of small focal lesion morphology determine the mammographic picture. Analysis of nodular shadows on the mammogram gives as a rule a possibility to differentiate between benign conditions (focal proliferation of the epithelium, fibroadenoma), early carcinoma (intraductal and lobular in situ, sometimes with small foci of invasion) and infiltrating carcinoma.
