LVI is indicative of unfavorable prognosis in the breast cancer—as manifested by increased local failure and reduced overall survival. It is for this reason that LVI is routinely included in the evaluation and reporting of all breast cancers. There are a variety of interpretative difficulties in the histopathologic assessment of LVI, and the clinical implications of any misinterpretation can be profound. This brief review seeks to highlight the difficulties in the evaluation of LVI in breast cancer. © 2006 Lippincott Williams & Wilkins, Inc.
