Photodynamic Therapy for the Local Control of Refractory Cutaneous Sarcoidosis of the Head: Case Report and Review of the Literature

We present a 65-year-old woman with a 10-year history of cutaneous sarcoidosis, refractory to multiple immunosuppressants and biologics. After 10 sessions of conventional photodynamic therapy (PDT) and 6 sessions of daylight PDT, we achieved a satisfactory local control of the lesion, reducing the thickness and orange coloration of the plaque and preventing superinfections, although systemic treatment had to be maintained. PDT could be a useful therapeutic option for cutaneous sarcoidosis.
