Abstract
We report two cases of cutaneous atrophy that occurred following the treatment of poly-L-lactic acid (PLLA) filler nodules. The patients presented with cutaneous atrophy following corticosteroid injections performed by non-medical professionals in an attempt to treat nodules that appeared after PLLA injection in the neck. The explanation for the formation of these nodules is not well established yet and, in general, they are difficult to manage. Corticosteroid infiltration into the nodules can worsen their appearance, inducing cutaneous atrophy. For neck treatment, PLLA is significantly effective in collagen stimulation, but it is crucial to know the application technique and management of complications. Although this case series includes only two patients, we recommend managing the PLLA nodules and the cutaneous atrophy secondary to corticosteroid infiltration into PLLA nodules with a conservative, expectant approach. Level of Evidence: Level IV, case report study.
