[Facial foreign body granulomas after dermal injection of a polylactate-based implant for wrinkles].

New methods are constantly introduced for soft tissue augmentation to correction of scars and wrinkles. Each method has its advantages and disadvantages. A 48 year old woman developed visible and palpable plaques and papules after treatment of the nasolabial and glabella folds with a poly L-lactic acid implant. Histological examination revealed a foreign body granuloma, while electron microscopy showed remnants of the implant material, demonstrating that poly L-lactic acid can also induce a foreign body reaction.
