Anthropometric and biochemical features were retrospectively evaluated in 12 patients with pseudohypoparathyroidism, Albright hereditary osteodystrophy, and multi-hormone resistance. Hypothyroidism and subcutaneous calcifications were presenting features in younger children. Temporal trends in stimulatory hormone resistance included early thyroid-stimulating hormone elevation and progression from parathyroid hormone elevation to hyperphosphatemia and hypocalcemia.
