PRIMARY NON-HODGKIN LYMPHOMA OF THE BREAST - A CASE REPORT AND REVIEW OF LITERATURE

BACKGROUND Primary breast lymphoma (PBL) is a rare but well-defined subtype of non-Hodgkin lymphoma (NHL) representing 0.5% of all malignant breast tumours, 1% of NHL and 2% of extra-nodal lymphomas. 1 However, primary NHL (PNHL) is the most frequent hematopoietic tumour of the breast with diffuse large B-cell lymphoma (DLBCL) as the most common histological type. 2 Clinical picture and imaging mimics carcinoma breast and diagnosis is usually established on biopsy. Chemotherapy and radiotherapy is the mainstay of treatment. The role of surgery is limited to biopsy to establish the correct histological diagnosis.
