The plasma immunoreactive parathyroid hormone level allows the diagnostic. This case, with diffuse hyperplasia of water-clear cells type, develops rickets of vitamin D deficiency before surgery. A large parathyroidectomy (7/8) was performed and the child is normo-calcemic 2 years after. The time of surgery is function of calcium level.
