Cutaneous and Ganglion Sarcoidosis Induced by Polycaprolactone Facial Filler: A New Expression of ASIA Syndrome?

Dermal fillers are applied using a minimally invasive technique with a good safety profile. However, they can have side effects. We present the case of a patient who, 2 months after undergoing polycaprolactone (Ellansé ) injections, developed nodular facial and nodal lesions that were compatible with sarcoidosis on histology. This complication has not been previously described for polycaprolactone and could be the expression of an autoimmune syndrome induced by adjuvants. Autoimmune/autoinflammatory syndrome induced by adjuvants (ASIA) is a recently devised umbrella term for autoimmune diseases caused by adjuvants.Aesthetic procedures, which are increasingly common, may be a cause of ASIA syndrome.Polycaprolactone is a bioabsorbable polymer with a safe profile but can have adverse events, including systemic sarcoidosis.
