[Adverse reaction to fillers. Diagnosis and management].

Injectable fillers are an established component of aesthetic medicine. In general they are safe to use. However, adverse reactions are possible for the whole spectrum of products. These reactions can occur immediately, subacute or delayed, e.g. after years. Erythema, edema, abscesses, nodule formation or even ulcerations can be observed. A correct diagnoses of these reactions is important to allow an appropriate treatment, taking into consideration the clinic, the injected material and if applicable other diseases/treatments that might contribute to these reactions. All of these reactions should be reported either to specialized registries and/or to the appropriate national agencies. Only then will we be able to learn more about these reactions and the best possible treatment.
