Background: Cosmetic filler injections are now a very common procedure for aesthetic purposes. Today no contra-indication is given anymore to any patient for an intradermal filling.
Objectives: We draw attention to a possible side effect of facial fillers in a population at risk.
Results: We report 2 similar cases of systemic sarcoidosis in patients who both developed a sarcoidal granuloma at the location of a cosmetic filler injection during combined interferon and ribavirin treatment for chronic hepatitis C infection. Cosmetic fillers were hyaluronic acid for one patient and probably silicone for the other.
Conclusion: Patients with chronic hepatitis C have a higher risk of interferon-induced sarcoidosis. Physicians must be aware of the risk that a granuloma can develop after a dermal filler injection especially in patients treated with interferon for chronic hepatitis C. These reactions may reveal a systemic sarcoidosis. We propose to perform a test for a hepatitis C virus infection before injecting a dermal filler and to inform the patient of this risk in case of a hepatitis C infection that could necessitate an interferon treatment.
