Management of intraductal papillomas of the breast: an analysis of 129 cases and their outcome.

Introduction: The management of intraductal papillomas of the breast has been controversial; some advocate surgical excision of all lesions despite benign pathologic features, whereas others excise only those specimens with atypia.
Methods: We conducted a retrospective review of 129 core-biopsy-proven papillomas of the breast with atypia (n = 43) and without atypia (n = 86) and determined the rate of missed carcinoma in surgically excised specimen in each group.
Results: Carcinoma was found in 22.5% of the surgically excised specimens in the atypia group (9/40) and in 3% of the surgically excised specimens in the no atypia group (1/29).
Conclusions: Our findings confirm the practice that papillomas with atypical features should be excised, and suggest that in patients with adequate follow-up, benign papillomas may be managed conservatively.
