Multiple papillomas of the breast: is current management adequate?

Multiple papillomas (MP) are subject to debate in terms of their clinical and pathological significance and management. To date the ideal management is still not well established. The Royal Perth Hospital Multidisciplinary Breast Service has prospectively accrued clinical and pathological data on over 9000 patients since 1994. The database was interrogated and all pathology reports retrospectively reviewed. A total of 23 cases with the diagnosis of MP were retrieved from the database between 1994 and 2004. Of these 23 cases, 13 (56.5%) were diagnosed by core biopsy, nine (39.1%) on excision biopsy, and one (4.4%) on a mastectomy specimen. The average age of patients was 56.4 years (range 44-74 years). The average duration of follow up is 4.1 years (range 1-10 years). In our series a close association with malignancy was noted for MP, which was also associated with a spectrum of proliferative breast disease. Contemporary guidelines should be developed for this controversial condition. We recommend that all patients with MP, especially when associated with atypia, undergo wide excision of the lesion with clear margins of at least 10mm and that these patients be monitored closely with annual imaging.
