Bilateral breast swelling in a pregnant woman with high-grade B-cell lymphoma, potentially Burkitt lymphoma

Primary breast Burkitt lymphoma is an aggressive subtype of non-Hodgkin lymphoma (NHL) and extremely rare. Burkitt lymphoma involving both breasts during pregnancy was a rare condition with fifteen cases reported in literature. We present a case of a 19-year-old 36 weeks pregnant woman who came for a check-up due to bilateral breast swelling. The final pathology with immunohistochemistry staining was high-grade B-cell lymphoma, potentially Burkitt lymphoma.
