title: Diabetes due to recurrent pancreatitis secondary to hypercalcemia due to primary hyperparathyroidism.
abstract: Acute pancreatitis due to hypercalcemia associated with hyperparathyroidism (HPT) is not very common. We herein report a case of a 21-year-old woman, who presented with acute pancreatitis. She had a past history of recurrent nephrolithiasis. Subsequent evaluation revealed hypercalcemia (serum calcium: 12.6 mg/dL); low phosphate (2.9 mg/dL) with elevated parathyroid hormone (PTH, 156.7 pg/mL) and HbA1c (6.9%). Diagnosis of primary HPT (PHPT) was made. Recurrent pancreatitis due to hypercalcemia may have resulted in diabetes mellitus.
