title: Multifocal primary breast lymphoma.
abstract: Primary breast lymphoma (PBL) is a rare condition, accounting for only 0.04 to 0.5% of breast malignancies and less than 2% of extranodal lymphomas. Clinical presentation and imaging may suggest a benign condition. Reports of treatment vary widely. Surgical therapy has been reported to include only biopsy or extend to partial mastectomy, total mastectomy, or even radical mastectomy. Chemotherapy with various agents is often used. Radiotherapy has been used in the adjuvant setting or as primary local therapy. Immunotherapy and radioimmunotherapy have shown some promise in other lymphomas and may be useful here as well. There is no standard or consensus of treatment for PBL. This report describes a case of multifocal PBL in a 45-year-old female and discusses the physical findings, diagnosis, and treatment options for this condition.
