Case report: A 40-year-old female patient presented with a lump in the right breast since 3 months progressively increasing to present size. Physical examination revealed a lump of 5 x 3 cm which is firm, well defined and mobile in the lower outer quadrant of right breast. FNAC was in favor of medullary carcinoma. MRM was done and sent for HPE, which revealed lymphoepithelioma like carcinoma of breast. Discussion: LELC of the breast is a rare histopathologic variant of breast carcinoma and is not a part of the world health organization (who) classification for breast cancer. Conclusion: Lymphoepithelioma-like carcinoma of the breast is an extremely rare entity with a favourable outcome when treated.
