AbstractPrimary breast lymphoma is a rare entity comprising 0.4-0.5% of all breast neoplasms. Diffuse large B-cell
lymphoma is the most common identifiable type of primary breast lymphoma with the usual presentation being that
of a painless palpable mass similar to breast carcinoma. A confirmed diagnosis is based on initial biopsy findings or
post-operative histopathology and immunohistochemistry (IHC) reports. The treatment options vary from surgical
interventions to chemotherapy and/or radiotherapy. However, there is no uptodate standard treatment guidelines
present. In view of this rarity, we herein report a case of a 25 year-old young woman who presented with primary
breast lymphoma of DLBCL variety.
