Incidental idiopathic calcinosis cutis in a rhytidectomy patient.

Calcinosis cutis, deposition of insoluble calcium salts in cutaneous tissues, is an uncommon disorder. This condition can be classified as metastatic, dystrophic, idiopathic, and iatrogenic based on the pathogenesis of the deposition. Whereas dystrophic calcinosis cutis is a fairly common condition, idiopathic cases are very rare. Distinct cutaneous anatomic areas, the vulva, scrotum, penis, and breast, have been reported to develop this disorder. Nevertheless, our case who had idiopathic calcinosis cutis in her neck may be a proof that this condition is not confined to genitals or the breasts and can be seen all over the skin.
