Benign papillomas diagnosed on large-gauge vacuum-assisted core needle biopsy which span <1.5 cm do not need surgical excision.

The objective of our study is to determine if a carefully selected subset of benign breast papillomas (size ≤1.5 cm) can be safely followed by imaging surveillance instead of immediate surgical excision. Over a 6½-year period, 86 breast lesions were diagnosed as a benign papilloma (BP) utilizing an 11- or 8-gauge vacuum-assisted core needle biopsy (VACNB) device. In general, it was our intent to remove as much of the radiologically evident lesion as possible. These 86 lesions underwent ≥2 years of imaging surveillance, without surgical excision following initial detection. With ≥2 years of radiologic follow-up, none of the 86 BPs demonstrated imaging findings that necessitated repeat biopsy or surgical excision. Benign breast papillomas ≤1.5 cm that are biopsied using an 11- or 8-gauge VACNB device with intent to remove as much of the radiologically evident lesion as possible are safe to undergo serial imaging surveillance rather than immediate surgical excision.
