[Diagnostic difficulties and limits in breast histopathology in core biopsies (breast microbiopsies)].

Core biopsy is increasingly used for the diagnosis and management of breast lesions. As a result, pathologists are being confronted with new difficulties pertaining to (1) the histological diagnosis on micro specimens (2) the correlation between core biopsy histological findings and mammographic findings, (3) the diagnostic significance of atypical hyperplasia on core biopsies, (4) the impact of tissue displacement on surgical specimens after needling procedures, and (5) the disagreement that can appear between the diagnostic on surgical specimen and on core biopsy.
