Suppurative granulomatous tattoo reaction: Complete remission with photodynamic therapy.

Tattoo complications are an increasing reason for dermatological consultation in recent years, becoming a therapeutic challenge in some cases. We present a case of a suppurative granulomatous reaction in a tattoo resistant to oral antibiotic and topical corticosteroid treatment that resolved after four sessions of photodynamic therapy (PDT) with methyl aminolevulinate, possibly due to its anti-inflammatory and antimicrobial action, with an excellent aesthetic result. We suggest that the clinical utility of PDT may be expanded to treatment of tattoo complications, as well as in cutaneous infections of unknown microorganisms resistant to antibiotics.
