[Non-epitherial malignant neoplasms of the breast--a clinicopathological study of 4 cases].
Between 1972 and 1981, 4 women with breast sarcoma underwent treatment at our department; they accounted for 1.1% (4 of 355) of all female breast malignancies. There was one case of malignant lymphoma and liposarcoma each, and 2 cases of malignant cystosarcoma phyllodes. The patients averaged 31.0 years of age. Of the two cases of cystosarcoma phyllodes, one had coexisting lobular carcinoma in situ arising in a fibroadenoma of the contralateral breast, the other had a coexisting lung cancer. Mastectomy was performed in 3 cases, irradiation in one (malignant lymphoma). All patients received concurrent chemotherapy. The regional lymph nodes were not involved, and 2 patients are alive and well without recurrence.
