Immobilization induced hypercalcemia is an uncommon and serious disorder that requires a thorough evaluation to exclude more common causes of an elevated calcium. Although the pathogenesis is not clearly illuminated, immobilization results in an uncoupling between osteogenic and osteoclastic factors that maintain bone homeostasis. When calcemic bone resorption overwhelms urinary calcium excretion, blood hypercalcemia ensues.

Persistent primary hyperparathyroidism is defined as the persistence or recurrence of hypercalcemia within 6 months of parathyroid surgery. Recurrent primary hyperparathyroidism is defined as the recurrence of primary hyperparathyroidism more than 6 months after an initially curative parathyroidectomy. In these situations, it is essential to rule out differential diagnoses, and in particular secondary hyperparathyroidism and familial hypocalciuric hypercalcemia.

Preoperative treatment of PHPT aims to 1) manage severe and/or symptomatic hypercalcemia and 2) prevent postoperative hypocalcemia. Severe hypercalcemia, defined as a blood calcium level ≥ 3.5 mmol/L, requires admission to hospital in a conventional or critical care unit, depending on clinical symptoms and comorbidities.

Background: Familial hypocalciuric hypercalcemia (FHH) is a rare, benign condition that shares characteristics with primary hyperparathyroidism (PHPT), a more sinister condition that requires surgical intervention. This case report demonstrates misdiagnosis of FHH and highlights important learning points to prevent this in the future.
Case Presentation: Hypercalcaemia was incidentally discovered in a 21-year-old patient who had no symptoms of hypercalcaemia and no significant family history.
Introduction: After kidney transplantation, persistent hyperparathyroidism commonly occurs, often alongside increased serum calcium levels. It is reasonable to infer that kidney transplant recipients (KTRs) with hypercalcemia related to persistent hyperparathyroidism are more susceptible to developing anemia. However, reports suggest that hypercalcemia could be a contributing factor to erythrocytosis.
