Treatment of calcinosis cutis with sodium thiosulfate therapy

Abstract

To the Editor: Calcinosis cutis (CC) is a rare cutaneous condition defined by abnormal depositions of insoluble calcium salts in the skin and subcutaneous tissue.1 Finding effective and safe treatments for these calcified lesions has been a known challenge among dermatologists. A variety of therapies have been reported, with limited success, including the treatment of CC with the use of warfarin, bisphosphonates, minocycline, intralesional corticosteroids, surgical excision, and carbon dioxide laser therapy.
