Liposarcoma of the breast. A case report.

Two cases are reported of liposarcoma of the breast, the first in a 62, and the second in a 60-year-old woman, respectively. The tumours were of the poorly differentiated, pleomorphic type and predominantly myxoid type, respectively. Liposarcoma of the breast is extremely rare, and including the present two cases, only 32 patients suffering from the condition have been described. It is difficult to make any prognosis owing to the small number of cases reported. Patient No. 1 in the present work, died 14 months postoperatively, owing to widespread metastatic tumour tissue infiltration of the spine, liver, as well as, the lungs; No. 2 lived for 17 years without signs of recurrence, until she died of carcinoma of the opposite breast.
