Lymphoepithelioma-like carcinoma (LELC) of the breast is a very rare tumor, and fewer than 20 cases have been reported. A recent report suggested the implication of human papilloma virus (HPV) in the pathogenesis of breast LELC. We report a case of LELC of the breast with a review of its relevance to an association with HPV. A 45-year-old female patient presented with a solid mass in the outer-upper part of her left breast, which was diagnosed as malignant (ductal carcinoma) by fine-needle aspiration cytology. The patient underwent a quadrantectomy of the breast and axillary sentinel node biopsy. Pathological examination revealed cohesive sheets or nests of malignant epithelial cells, with unclear circumscription in a background of diffuse lymphoid infiltration; the postsurgical clinical stage was pT1pN0M0, stage 1. Immunohistochemistry demonstrated that the tumor was triple negative and basal-like breast cancer. In the present case in situ hybridization demonstrated positive HPV signals in a few tumor cells; however, polymerase chain reaction study failed to detect HPV in tumor cells. CONCLUSION: To the best of our knowledge, this is the second report on HPV infection associated with breast LELC.

ABSTRACT: 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 21(st) 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.12/2014; 5(5):1107-1112.
