Lymphoma of the Breast

Abstract

Breast lymphomas represented 1.2% of all non-Hodgkin lymphomas in this study; the frequency of primary and secondary cases was equal. In both groups, right breast lesions were predominant, and the most frequent morphologic type was diffuse large B-cell lymphoma. Gene rearrangement analysis is helpful in selected cases to rule out bone marrow involvement, especially in older patients, in whom lymphoid aggregates are common.
