Primary Peripheral T-cell Lymphoma of the Breast: Radiologic and Pathologic Findings

Abstract

Primary breast lymphoma is a rare disease entity, particularly the T-cell type. There have been many case reports of primary breast lymphomas; however, these are mostly pathologic reports, with only a few reports in radiology literature. To the best of our knowledge, this is the first report on the radiologic features of primary T-cell type breast lymphoma, including mammography, ultrasonography, MR imaging, and 18 fluorodeoxyglucose positron emission tomography/computed tomography scan. The radiologic findings are rather unique for this T-cell lymphoma compared to B cell type.
