Pancreatitis in Association with Primary Hyperparathyroidism due to Ectopic Intrathymic Parathyroid Adenoma in a Pediatric Patient.

Primary hyperparathyroidism leads to increased serum parathyroid hormone levels resulting in hypercalcemia. Ectopic intrathymic parathyroid adenomas account for 6%-16% of all parathyroid adenomas and are rare in children but should be considered in cases with hypercalcemia. Early and timely diagnosis can preserve end-organ damage and bone and renal function.
