title: Bilateral non-Hodgkin's lymphoma of the breast mimicking mastitis.
abstract: We recently encountered a case of recurrent non-Hodgkin's lymphoma manifested after a long period of quiescence as bilateral involvement of the breasts. This 37-year-old woman had stage IVA nodular poorly differentiated lymphocytic lymphoma diagnosed 9 years previously and was followed up without treatment. She was lost to follow-up after 4 years but had been in good health until seen with malaise and fever and pain, swelling, and erythema involving both breasts. Biopsies of lymph node and bone marrow showed a high-grade non-Hodgkin's lymphoma (lymphoblastic lymphoma) of B cell origin with central nervous system involvement. Combination chemotherapy produced a dramatic remission, but the patient died of Pseudomonas septicemia.
