Primary Lymphoma of the Breast: Presentation of Two Cases

Abstract

Primary lymphoma of the breast is seen most frequently in the 6th decade and accounts for 0.04-0.5% of breast cancers. Diffuse large B-cell lymphoma is the most common histopathological type. Case 1: A 77-yearold female patient presenting with a painless mass in the breast. Case 2: A 32-year-old postpartum patient presenting with an ever-increasing fever for the past 3 months, night sweats and painful mass in the breast. Primary lymphoma of the breast might be confused clinically and radiologically with other breast cancers. Due to the difference between treatment protocols, a differential diagnosis must be made to distinguish it from other types of breast cancers. Pregnancy-related physiological changes complicate the diagnosis of the breast lymphoma. The cases of the lymphoma clinically mimicking mastitis may be even more complex.
