Intraductal migration of silicone from intact gel breast prostheses.

This case presents a previously undocumented complication of silicone gel prostheses in which silicone accumulated in the lactiferous ductal system of the breast with the underlying prostheses being intact. It demonstrates the disconcerting potential of silicone to migrate through tissue planes that are not disrupted. It also highlights the fact that a great deal of knowledge about the body's interaction with silicone still needs to be ascertained.
