Adenocarcinoma of the breast associated with silicone injections.

A 42-year-old woman developed inflammatory breast cancer in a breast with "silicone mastitis" 12 years after bilateral breast augmentation with liquid silicone injections. Despite aggressive local and systemic therapy, the patient died of her disease. Breast cancer arising in silicone-injected breasts is reported infrequently, and physicians caring for patients with silicone breast injection augmentation should be aware of this potentially fatal association with breast cancer.
