Surgical management of calcinosis cutis universalis in systemic lupus erythematosus

Calcinosis cutis is common in several connective tissue diseases but rare in systemic lupus erythematosus (SLE). A 43-year-old woman with a 12-year history of SLE who presented with calcinosis cutis at the time of SLE diagnosis developed a large, ulcerated, draining mass on her left hip. The lesion was excised and skin was grafted, with an excellent early result. The clinical variants and mechanisms of ectopic calcification are discussed, as well as the proposed medical therapies for calcinosis cutis.
