Lymphoma of the breast: A clinicopathologic analysis of 51 cases with a specific emphasis on patients with a history of breast carcinoma.

Abstract

We herein report our experience with 51 breast lymphoma (BL) cases from 46 patients with a specific focus on patients with a history of breast carcinoma. The overall most common subtype was diffuse large B-cell lymphoma, followed by MALT lymphoma and follicular lymphoma. Eleven of 46 (24%) patients had either previous history of or concurrent breast carcinoma. There was no significant difference in clinicopathologic characteristics between patients with primary and secondary BL. On follow-up, patients with secondary BL had a worse disease-free survival with no difference in overall survival between the two groups.
