Normal levels of PTH and calcium in serum, does not necessarily means healthy parathyroid glands, in autopsy reports large parathyroid glands in patients were found without the presence of hyperparathyroidism.There are also reports of parathyroid carcinomas with normal serum levels of calcium.
Niveles de PTH y calcio séricos normales no significan necesariamente paratiroides sanas, ya que estudios basados en reportes de autopsias han revelado paratiroides alargadas en pacientes sin hiperparatiroidismo. También hay reportes de carcinomas paratiroideos que han cursado con niveles séricos normales de calcio.
