Is surgical excision necessary in benign papillary lesions initially diagnosed at core biopsy?
Debate continues regarding the use of surgical excision in benign papillary lesions initially diagnosed at core biopsy. The objective of this study is to propose management guidelines for benign papillary breast lesions initially diagnosed at core biopsy. Between January 2003 and January 2006, 76 lesions were identified as benign papillary lesions at initial core needle biopsy (n=68) or vacuum biopsy (n=8). After surgical excision, six of the 68 benign papillary lesions initially diagnosed at core needle biopsy were confirmed as malignant papillary neoplasms, giving a false-negative rate of core needle biopsy of 8.8%. Three of the eight atypical papillomas initially diagnosed at core needle biopsy were confirmed as papillary cancer in final pathology, giving a false-negative rate of 37.5%. In the analysis of the difference between benign papillary lesions and atypia or malignant papillary lesions, malignant papillary lesions were located more peripherally (p=0.005) than benign lesions and were larger (>1.5 cm, p=0.017). It is concluded that atypical papillomas at initial core biopsy or large, clinically peripherally located papillomas (>1.5 cm) need additional surgical excision.
