title: Calcinosis cutis in a newborn with transient pseudohypoparathyroidism.
abstract: Pseudohypoparathyroidism (PHP) is a heterogenous group of disorders characterized by hypocalcemia with hyperphosphatemia, increased serum concentration of parathyroid hormone (PTH), and insensitivity to the biological activity of PTH. Calcinosis cutis, the cutaneous deposition of calcium salts in the dermis, is a rare clinical symptom in infancy. The deposition of calcium in the skin may be classified as dystrophic, metastatic, idiopathic, and iatrogenic. Although a few infants with PHP and calcinosis cutis have been reported, to the authors' knowledge, the combination of neonatal transient PHP and calcinosis cutis associated with calcium treatment has not been previously reported. The authors report a newborn boy with transient PHP presenting with early hypocalcemia, hyperphosphatemia, increased PTH levels, and calcinosis cutis after intravenous treatment of calcium gluconate.
