title: Synchronous carcinoma and lymphoma of the breast.
abstract: Primary breast lymphoma is a rare entity. Furthermore, extranodal marginal zone B-cell lymphoma affecting the breast is exceedingly rare. We report a unique case of invasive lobular carcinoma diagnosed simultaneously with an extranodal marginal zone B-cell lymphoma of the breast. A literature review demonstrated 2 reports of synchronous invasive ductal carcinoma and mucosa-associated lymphoid tissue lymphoma affecting the breast; however, there is a paucity of cases demonstrating different malignancies affecting the same breast tissue in a particular patient, especially in the setting of lobular carcinoma. As such, there are no clear guidelines on the optimal management of such synchronous tumors. Herein, the diagnostic and management issues are explored.
