Breast involvement by malignant lymphoma either as a primary site or as a secondary site from lymphoma elsewhere is rare. Primary breast lymphoma (PBL) accounts for only a small percentage of total malignant lymphoma involving the breast. The incidence of PBL varies from 0.004% to 0.5%. We present a case of PBL which was well demonstrated on total-body imaging as well as SPECT using 67Ga-citrate.
