A case of diffuse large B-cell lymphoma clinically and pathologically confused with breast cancer A case of lymphoma that is confused with breast cancer

Abstract

Primary breast lymphoma is defined as only the presence of disease in the breast without in any other region of the body. Diffuse large B cell lymphoma (DLBCL) is most common among lymphoma types and accounts for approximately 50% of cases. We presented a case that was evaluated as breast cancer after initial pathological reports but diagnosed with DLBCL in further examinations. A 56-year-old woman with breast and axillary mass complaint who was initially evaluated as breast carcinoma and started treatment accordingly was presented. Due to clinical and pathological suspicion, biopsies repeated. The performed tru-cut breast biopsies were found to be compatible with DLBCL. In cases where adequate immunohistochemical examinations cannot be performed or there are conflicting data in the pathology reports, it is very important for the differential diagnosis to be evaluated together with the clinic and in case of doubt, biopsy repeats and pathology samples are re-examined in advanced centers.
