Calcinosis Cutis of the Vulva: A Review.

Idiopathic calcinosis cutis (CC) is an uncommon skin condition. Although it has been reported many times in the scrotum, it is exceedingly rare in the vulva. Most reports of vulvar CC are in children. Vulvar CC may be thought clinically to be inclusion cysts. Other causes of calcinosis such as autoimmune disease or alterations in serum calcium levels, potentially associated with malignancy, must be considered before considering a case as idiopathic.
