Morphea-like discoid lupus erythematosus in a patient with a history of polyacrylamide gel injection: A case report.

Background: Discoid lupus erythematosus (DLE) is an autoimmune disease with multifactor etiology which develops in genetically susceptible patients. Rarely, DLE lesions can mimic other connective tissue disorders such as morphea. The growing application of soft tissue fillers is associated with increasing complications. Some substances used for soft tissue augmentation such as silicon implants may trigger lupus erythematosus diseases.

Case Report: Here we report a case of morphea-like discoid lupus erythematosus developed several years after polyacrylamide dermal filler (PAAG) injection for facial rejuvenation.

Conclusion: As noninvasive procedures like dermal filler injections are increasing worldwide, physicians may consider the long-term probable side effects of these compounds.
