1. Benign Breast Papilloma without Atypia: Outcomes of Surgical Excision versus US-guided Directional Vacuum-assisted Removal or US Follow-up
For benign papilloma without atypia, the upgrade rate to malignancy was 1.9% after surgery, 2.1% after US-guided directional vacuum-assisted removal (DVAR), and 0% with US follow-up without intervention (P = .80)
The recurrence rate after US-guided DVAR was 3.6%; all recurrences were confirmed as benign at surgery.
In the group with US follow-up without intervention, 59 of the 61 lesions (97%) remained stable in size with no growth during a mean follow-up of 43.3 months; two lesions increased in size and were confirmed as benign at surgery.
In a 42-year-old with bloody nipple discharge, A, mammography shows an oval mass (arrow). B, US shows a hypoechoic solid mass (arrows) with ductal dilatation. DVAR yielded a benign papilloma. Follow-up imaging showed no recurrence.
