Case ReportBreast lymphoma in a patient with B-cell Non Hodgkin Lymphoma: A case report study

•Breast involvement in Non Hodgkin Lymphoma is a rare entity.•Breast lymphomas represent localized extranodal Primary or Secondary lymphomas.•Physical examination is paramount for discovering lesions.•Preoperative diagnosis ensures avoidance of unnecessary interventions.•Breast lymphomas should be considered in the differential diagnosis of breast neoplasms.

IntroductionBreast involvement in Non Hodgkin Lymphoma is a rare entity as it accounts for 2.2% of all extranodal lymphomas.Presentation of caseA 59-year-old woman was referred to our Breast Unit because of two nodules of the right breast newly discovered during her annual mammography. Moreover, during the physical examination, a red-brown itchy lump of the scalp was discovered. The punch biopsies of the scalp lesion and ultrasound-guided core biopsies of both nodules of the right breast, revealed the presence of diffuse large B-cell Non Hodgkin Lymphoma in all tissue specimen sites.DiscussionBreast lymphomas represent an uncommon form of localized extranodal lymphomas that can be classified as Primary (PBL) or Secondary (SBL) breast lymphomas.ConclusionThe value of preoperative diagnosis should be underlined as the patient avoids unnecessary surgical intervention and has earlier initiation of chemotherapy.
