Liposarcoma of the breast, review of the literature and a report of a case.

A case of gigantic liposarcoma of the breast in a 52-year-old woman was reported. She had a small indolent mass in the left breast for twenty years. The mass grew rapidly from the summer of 1979 and became gigantic and penetrated the skin over the mass. Her general condition on admission was poor but resection of the tumor was carried out. She suddenly died of cardiac failure with electrolytes imbalance 13 days after the operation. The diagnoses of liposarcoma, predominantly myxoid, was made on the basis of light and electron microscopic findings. Forty cases of liposarcoma of the breast were collected from the literature. The possibility of malignant transformation of a benign tumor was suggested.
