Reviewing the Evidence to Guide Clinical Care: Proliferative Breast Lesions in Breast Reduction Specimens.

The number of reduction mammoplasties performed in the United States continues to increase annually. Given the high incidence of breast cancer in women, it is routine practice for breast tissue excised during routine breast reductions procedures to be sent for pathology review. During pathology assessment, occult malignancy and on-occasion proliferative breast lesions of unknown and/or variable malignancy may also be present. We provide a review of commonly diagnosed atypical proliferative breast lesions in breast reduction specimens and a guide to plastic surgeons for further management.
