Answer

Non-Hodgkin lymphoma of the breast is rare and usually secondary to involvement elsewhere in the body. Primary lymphoma may be synchronously or metachronously bilateral; in some cases, it grows rapidly and forms a large mass. These tumors can be occasionally confused with an invasive carcinoma, particularly if only needle-biopsy specimens are examined. Breast MRI can help in determining the intramammary extent of disease and may be useful for monitoring the response to chemotherapy.
