Primary Bilateral Malignant Non-Hodgkin’s Lymphoma of the Breast: A Case Report and Review of the Literature

Abstract

Primary breast lymphoma (PBL) is considered a rare clinical entity, representing approximately 0.4% to 0.5% of all breast tumors. In this report, we present a case of Primary breast lymphoma in a 19-year-old woman complaining of a lump in the right breast and a nodule in the left breast. Breast imaging pointed towards PBL which was confirmed by the results of immunohistochemistry. The case was eventually diagnosed as non-Hodgkin's type B lymphoma. The management of PBL and carcinomas is completely different. The value of preoperative diagnosis should be emphasized, as the patient avoids unnecessary surgery and begins chemotherapy earlier.
