Key clinical message:
Primary breast lymphomas are a very rare group of breast malignancies
and account for 2.2% of all extra nodal lymphomas and for 0.04% to
0.5% of malignant breast neoplasms. Most of the cases are diffuse large
B-cell non-Hodgkin’s lymphoma with T-cell, MALT and Burkett’s Lymphoma
being further uncommon. Imaging findings in lymphoma are nonspecific and
whole body imaging is an essential part of the workup to rule out
disease in other parts of the body and to be labelled as primary breast
lymphoma. Here we present a rare case of primary B-cell lymphoma
involving bilateral breasts and presenting as multiple nodular masses.
