Lymphoepithelioma-like carcinoma (LELC) is a rare type of neoplasm in which only twenty cases have been reported in the breast. This type of tumor can be difficult to distinguish from other breast tumors particularly medullary carcinoma and lymphoma in the breast. We present a case of LELC of the breast presenting as an abscess along with a review of the literature. This is the 21st reported case of LELC of the breast and the first case to present as an abscess. Her clinical picture could have been mistaken for other infectious or inflammatory diseases. Given the potential for favorable outcome, early detection and general knowledge of this neoplasm are essential to expedite treatment for this rare tumor type.
Core tip: We present a case of lymphoepithelioma-like carcinoma (LELC) of the breast, which is a rare tumor type that can be difficult to diagnose. This particular case is the first case of LELC of the breast presenting as an abscess with radiologic and histologic studies as well as literature review of this rare tumor.
