Hematologic malignancies of the breast: report of three cases.

Involvement of the breast by hematologic malignancies is rare and remains an important diagnostic challenge for radiologists. We present the cases of 3 patients diagnosed with hematologic breast malignancies at our institutions. All cases were diagnosed by breast core biopsies, which revealed 2 cases of diffuse B-cell lymphoma and one case of myeloid sarcoma associated with acute myeloblastic leukemia (AML). This study focuses on describing the diagnostic features found on mammographic and sonographic imaging at initial presentation of lymphomas and leukemias affecting the breast.
