Lymphoepithelioma-Like Carcinoma of the Breast: A Diagnostic and Therapeutic Challenge

Abstract

We present a patient with lymphoepithelioma-like carcinoma (LELC) of the breast whose diagnosis is illustrative of the pathology nuances that must be taken into account to successfully reach correct identification of the disease. We also present an overview of our patient’s proposed treatment in the context of 16 other reported LELC cases. Although LELC cases are rare, a sufficient number have been reported to discern the natural history of this pathologic entity and to undertake a review of those cases and of the application of oncologic first principles in their management. Given the potential for locoregional spread and distant metastases in LELC, adjuvant therapy has a role in the treatment of this entity.
