An Unusual Case of Marginal Zone B-Cell Lymphoma Arising in the Breast – Its Diagnosis and the Role of Radiotherapy in its Management

摘要

Primary lymphoma of the breast accounts for 0.04–0.5% of all breast malignancies and approximately 1% of all extranodal lymphomas. For stage IE node-negative disease, involved field radiotherapy is recommended except for very young women in whom the risk of breast cancer is a concern. The rate of complete response for limited stage extranodal marginal B-cell lymphoma is in excess of 90%.
