Tissue degeneration 7 years after breast augmentation with injected polyacrylamide hydrogel (PAAG).

Injectable polyacrylamide hydrogel (PAAG) is a jelly-like transparent implant used in breast augmentations. This type of implant had been used since 1998, but its use was prohibited in China in 2006 due to numerous complications that had arisen from its use. In one case, a rare appearance of PAAG tissue degeneration was observed 7 years after an injectable breast augmentation using PAAG.
