A patient with hypercalcemia and newly diagnosed multiple myeloma developed acute pancreatitis. Other etiologic factors for pancreatitis were excluded. Hypercalcemia secondary to hyperparathyroidism is associated with acute pancreatitis. In English literature, only one other case has been published where the hypercalcemia of multiple myeloma may have caused pancreatitis. Pancreatitis should be considered in patients with hypercalcemia and multiple myeloma who develop nausea/vomiting, and abdominal pain.
