Percutaneous excisional biopsy of palpable breast masses under ultrasound visualization.

A palpable breast mass is a common reason for surgical consultation. Our goal was to determine whether ultrasound-guided vacuum-assisted core biopsy (US-VACB) is safe and effective in completely removing presumed benign palpable breast masses. We conducted a cohort study of 201 consecutive patients with presumed benign palpable masses who underwent removal with US-VACB. The main outcome measured was the successful removal of palpable masses. Palpable masses were successfully removed with US-VACB in 99% of cases; 2% were cancer and 7.5% were atypical ductal hyperplasia or phyllodes tumor. Two clinical recurrences representing a seroma were seen on follow-up. US-VACB is safe and effective in the initial diagnosis and management of presumed benign palpable breast masses. It provides the benefits of percutaneous biopsy and the palpable abnormality no longer remains.
