Abstract

Lymphoepithelioma-like carcinoma carries similar histopathological features with lymphoepithelioma typically located in the nasopharynx. Lymphoepithelioma-like carcinoma of the breast can be mistaken for breast lymphoma or medullary carcinoma due to the undifferentiated appearance of tumor cells and presence of prominent lymphoid component. Lymphoepithelioma-like carcinoma is rare, and the similarity between medullary carcinoma of the breast makes it difficult to distinguish these two tumors. In the presented case, neither lymph node nor distant metastases were detected. Breast lymphoepithelioma-like carcinoma is extremely rare with only 21 reported cases in the literature. Herein we present a 59-year-old woman with lymphoepithelioma-like carcinoma of the breast along with the cases previously published in the literature.

Keywords: Breast carcinoma; lymphoepithelioma; lymphoepithelioma-like carcinoma.
