Pathological problems of intraoperative diagnosis in sclero-elastotic lesions of the breast.

The Author describes pathological problems of the diagnosis, at frozen section, of non invasive lesions of the breast, classified according to "consensus meeting" on the preneoplastic significance of fibrocystic disease. Sclero-elastotic lesions are treated with special interest and the main differential diagnoses are discussed. This lesion is considered to be benign and the relative risk of developing infiltrating carcinoma depends on the features of the epithelial component similar to fibrocystic disease whose sclero-elastotic lesion is likely to be a morphological variant.
