The Authors describe the case of a 40-year-old woman with a ruptured carboxi-methyl-cellulose mammary implant. The utilisation of this type of implants will spread rapidly, so it is very important to diffuse knowledge about these. The Authors conclude that carboxi-methyl-cellulose hydrogel, as a filler, is a valid alternative to silicone and saline solution (4, 5).
