Background: To determine concordant or discordant breast biopsy results and see their effect on patient management and outcome.

Material and methods: This descriptive analytical study was conducted at the department of Diagnostic Radiology Aga Khan University Hospital Karachi Pakistan from January to December 2013. All patients fulfilling our selection criteria were included. A concordant result was defined when the imaging and pathology results concluded same diagnosis and a discordant result when they did not match. All histopathology results were reviewed and a decision was made regarding concordant/discordant biopsy results and recommendations given for further management of all patients.

Results: A total of 282 patients underwent core biopsy of lesions in the breast. The mean age was 47.87 ± 13.99 years. Out of 282 lesions biopsied, 172 were concordant malignant and 105 were concordant benign. Two lesion out of 282 were borderline or high risk, one case was discordant benign and 2 cases discordant malignant. The appropriate management for all cases was recommended after radiology-pathology correlation.

Conclusion: Cautious Radiology-Pathology co relation is indispensable in addition to appropriate post biopsy management for managing a successful core breast biopsy program. This practice identifies a substantial number of false negative results of core biopsy by identifying discordant results avoiding delays in diagnosis of breast cancer.
