Primary lymphoma of the breast: MR imaging features. A case report

Magnetic resonance imaging of primary breast lymphoma

“…Primary breast lymphoma is defined by pathologists and clinicians as primarily mammary lymphomatous involvement with or without spread to regional lymph nodes [2,4]. Breast lymphoma, either primary or secondary site of disease, is uncommon, representing 0.04%-0.53% of all mammary malignancies [5,16].…”

“…Mammographic and ultrasonographic imaging findings of PBNHL have been reported to be nonspecific [2,3], whereas MRI findings have been described in single case reports [4][5][6][7][8] or in a study analysing multiple diagnostic modalities, where MRI was performed in one case only [9].…”

Primary Non-Hodgkin Lymphoma of the Breast- A Rare Case Report

“…Primary breast lymphoma has a reported incidence ranging from 0.04-0.5% of malignant breast neoplasms [5] of all extra nodal NHL and 0.7% of all NHL. [6] Histologically, primary breast lymphoma is predominantly of B-cell origin with most common subtype being diffuse large B-cell type, [7] as in our case. There is a slight predilection for the right breast, but the explanation for this remains unclear.…”

Primary Mammary (Non-Hodgkin) Lymphoma of Breast: A Case Report

“…Primary NHL of the breast is a rare disease, representing only 0.04%-0.50% of malignant breast neoplasms, [6] 1.7% of all extranodal NHL and 0.7% of all NHL [7]. Histologically, primary breast lymphoma is predominately of B-cell origin and most commonly large cell type [8]. Numerous authors have found that lymphoma occurs more frequently in the right breast and that the rate of secondary lymphoma metastatic to the breast only slightly exceeds primary breast involvement [8,9].…”

“…Histologically, primary breast lymphoma is predominately of B-cell origin and most commonly large cell type [8]. Numerous authors have found that lymphoma occurs more frequently in the right breast and that the rate of secondary lymphoma metastatic to the breast only slightly exceeds primary breast involvement [8,9]. Primary NHL presents most commonly as a palpable mass [10].…”
