Calcinosis cutis may be a complication of administration of intravenous calcium solutions. We report four patients who developed calcinosis cutis following orthotopic liver transplantation, all of whom had received calcium chloride solutions intravenously during surgery. There was no evidence of extravasation of the solutions. A gradual improvement of the lesions was seen in the subsequent months. This complication of intravenous calcium infusions is probably related to the large amounts of blood-derived products and of calcium salts administered during surgery.
