Benign intraductal papilloma: diagnosis and removal at stereotactic vacuum-assisted directional biopsy guided by galactography.

Galactography was performed in women who had problematic nipple discharge. In five women who had a focal intraductal filling defect, immediate stereotactic vacuum-assisted directional biopsy of the filling defect was performed; results were a benign intraductal papilloma in each, with atypia in one. In the four women who did not have atypia, the procedure was diagnostic and appears to have been therapeutic as well, since nipple discharge ceased after the procedure.
