Bilateral breast lymphoma: a case report from Lao PDR

Abstract

Primary breast lymphoma, a rare malignant neoplasm, represents 1–2% of all non-Hodgkin lymphomas and less than 0.5% of all malignant neoplasm of the breast. Only about 6% of the patients with primary breast lymphoma had bilateral involvement. Breast lymphomas are mostly of B lineage, and the most common subtype is diffuse large B cell lymphoma. The patients with primary breast lymphoma are women, range from 13–90 years of age at diagnosis (average 55 years) with bimodal peaks in the mid 30 s and mid 60 s. We report a 39-year-old woman with bilateral breast diffuse large B cell lymphoma who presented with rapid growing masses in both breasts for two months and had bilateral modified radical mastectomy performed.
