title: Hypophosphatemic rickets, hyperparathyroidism, and hyperthyroidism with hypercalcemia.
abstract: We describe a case of hypophosphatemic rickets in which hyperparathyroidism and hypercalcemia developed and were possibly secondary to co-existent hyperthyroidism. During the period of hypercalcemia with high immunoreactive parathyroid hormone levels the serum inorganic phosphorus level became, and remained, normal. This supports the concept that renal tubular phosphate absorption may be sensitive to calcium.
