PTHLH and hypercalcemia disease: Lescuyer et al. [59] presented a 29-year-old female (without a diagnosis of hypoparathyroidism) at three months postpartum (lactating) with hypercalcemia (3.09 mmol/L) (12.38 mg/dL), suppressed PTH and elevated PTHrP; the authors note upon weaning serum calcium normalized (2.34 mmol/L) (9.38 mg/dL) and PTHrP became undetectable.
