Fingertip calcinosis cutis.

ABSTRACT

Calcinosis cutis, a rare disorder caused by an abnormal deposit of calcium phosphate into the skin, is observed in a variety of disorders. Peculiar conditions feature skin calcifications in children and may have an iatrogenic origin. The unusual case of a baby showing periodic transepidermal elimination of calcified nodules from her fingertips is reported. In this case, fingertip calcinosis cutis was probably caused by ischemic damage due to the venous obstruction that occurred during intensive care in the neonatal period.
