Extranodal marginal zone lymphoma (EMZL) is a low-grade subtype of B-cell non-Hodgkin lymphoma that can affect any mucosal tissue, most commonly the GI tract. Primary involvement of the breast, known as primary breast lymphoma (PBL), is a very rare manifestation. We report an unusual case of a 65-year-old woman with primary breast EMZL presenting as calcifications discovered during screening mammography. This represents an exceedingly atypical appearance of primary breast lymphoma that is rarely described in the literature.
