A Comparative Study of the Efficacy of Intralesional Sodium Thiosulfate Versus Intralesional Normal Saline for the Treatment of Dystrophic and Idiopathic Calcinosis Cutis, A Double-Blind Randomized Placebo-Controlled Trial

The purpose of our research is to compare the effectiveness of 125mg/50ml sodium thiosulfate (STS) solution to normal saline (0.9% sodium chloride) when injected intralesionally for the treatment of calcinosis cutis. Our specific aim is to assess the response of dystrophic and idiopathic calcinosis cutis to the injections of sodium thiosulfate in our patients.
