The purpose of this study was to determine the accuracy of core needle biopsy (CNB) diagnoses of papillary breast lesions, and to identify the risk factors and histologic features, compared with excisional biopsy (EB).


We retrospectively reviewed 1,682 sonographically guided core needle biopsies performed at one single medical center from January 2001 through December 2005, and identified 41 papillary lesions. Surgical correlation was available for 35 cases, 2 cases were loss follow-up and 4 cases diagnosed as papilloma by core needle biopsy were followed up with imaging for at least 24 months.


The pathologic diagnoses for the 35 papillary lesions obtained at core biopsy were benign in 24 cases, atypical in 7, and malignant in 4. Of those diagnosed as benign lesions at CNB, 7/24 turned out to be malignant. In the hyperplasia group, 5/7 were malignant. The total upgrade rate was 39%. The positive predict value was 100% and negative predict value was 61%.


All papillary lesions of the breast diagnosed by CNB should be excised because a substantial number of lesions were upgraded of diagnoses at excision.
