Recalcitrant digital calcinosis cutis successfully treated with intralesional sodium thiosulfate under digital nerve blockade.

Dystrophic calcinosis cutis can be associated with severe pain, decreased mobility, increased risk of infection and significantly decreased quality of life. We report a case of recalcitrant calcinosis cutis on the background of eosinophilic fasciitis, which achieved rapid reduction in calcium deposits following a novel injecting protocol of intralesional sodium thiosulfate.
