Lip silicone granulomatous foreign body reaction treated with aldara (imiquimod 5%)

We report a case of a lip granulomatous reaction after injection of silicone being treated successfully with topical Aldara (Imiquimod 5%). Silicone granulomas and the inflammatory foreign body reaction that can occur are some of the complications that arise from using silicone for cosmetic enhancement. The inflammatory reaction of this patient first appeared shortly after silicone injection of both the upper and lower lips. Histopathologic examination revealed a foreign body inflammatory reaction that is consistent with silicone granuloma. Although this reaction has been described extensively in the dermatologic literature as one of the disfiguring side effects of silicone injection, its treatment has plagued cosmetic dermatologists. We report the use of an immunomodulatory cream Aldara (Imiquimod 5%) to treat this type of reaction.
