[IDIOPATHIC HYPERCALCEMIA IN THE CHILD: 2 NEW CASES AND REVIEW OF THE LITERATURE].

Several reports of idiopathic hypercalcemia of childhood have been published since Lightwood in 1932 described dwarfism associated with mental retardation, strabismus, hypercalcemia, nephrocalcinosis and osteosclerosis. The present paper adds two new cases. The first patient was 15 months old when first seen with stunted physical and mental growth, a systolic murmur, and a serum calcium value of 13 mg. %. This child suffered several severe infections and in spite of a low calcium intake and the administration of chelating agents her blood calcium rose until death six months later. The other patient, three years old, also had delayed physical and mental development, typical facies, a systolic murmur, skeletal lesions, and nephrocalcinosis. Varied therapeutic attempts failed. Idiopathic hypercalcemia of childhood is reviewed in the light of the 94 reports already published.
