Carcinoma of breast co-existing with non-Hodgkin's lymphoma of axillary lymph nodes

The co-existence of breast carcinoma and lymphoma in the axillary lymph nodes, without a history of previous chemotherapy or radiotherapy is rarely described. We present a case of a 50-year-old female with right breast mass, proved by pathological examination to be invasive mucinous carcinoma. Examination of the axillary lymph nodes as axillary clearance showed concomitant small lymphocytic lymphoma and chronic lymphocytic leukemia, with no evidence of metastatic mammary carcinoma deposits.
