Primary breast lymphoma has been defined as localized involvement of one or both breasts with or without ipsilateral axillary nodal involvement, usually as a rare manifestation of extranodal non-Hodgkin's lymphoma. We describe three cases of this uncommon disease seen at our institution. Two of these cases presented as palpable breast lumps and one was screening detected. None of the patients had a prior history of lymphoma; only one reported B symptoms night sweats and weight loss. Diagnosis was established on ultrasound-guided core biopsy and no evidence of metastatic disease was identified. Even though the imaging features are not specific to this diagnosis, the radiologists should be aware of the clinical and imaging presentation of this rare malignancy to recommend appropriate management and establish radiologic–pathologic concordance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
