Comparative evaluation of breast lesions with the help of impression smears, histopathology and mammography

A total of 148 surgically removed benign and malignant breast lesions were studied to correlate cytomorphologial features in impression smears and histopathological sections. Mammograms were taken prior to surgery. Role of mammography in detection of non-palpable breast lesions was enlightened. Impression smears helped in quick diagnosis (intraoperative) and overall accuracy obtained was 97.4%. Cluster predominant and Grade II nuclear grading on smear pattern was seen in 58.8% and 57.4% cases respectively amongst the 68 malignant cases. 45% cases revealed non-palpable breast lesions on mammography which was later confirmed on histopathology.
