Bilateral lymphosarcoma of the breast.

A case is presented of bilateral lymphosarcoma of the breast in a 77-year-old woman. The pre-admission surgical history recorded a mastectomy in July 1972, for lymphosarcoma of the right breast. She had been well until shortly before admission in March 1974 because of a tumor in her left breast. This proved to be lymphosarcoma. Treatment consisted of a left mastectomy. At that time there were no signs of axillary or systemic involvement. Later, evidence of systemic lymphosarcomatosis necessitated starting chemotherapy.
