Obstructive chronic pancreatitis with transient eosinophilia in a 13-year-old child

Obstructive chronic pancreatitis in children occurs as a result of congenital or acquired stricture of the pancreatic duct. The prominent histologic changes are characterized by periductal fibrosis and subsequent ductal dilatation. Diagnosis is usually made by imaging studies such as endoscopic retrograde cholangiopancreaticography, ultrasonography, and pancreatic function testing. Eosinophilia is frequently associated with allergic rhinitis, asthma, parasitic infections, and drug reactions. It has been infrequently described with chronic obstructive pancreatic diseases. In this article, we present a patient with eosinophilia and abdominal pain with chronic obstructive pancreatitis. In our case, the symptoms of pancreatitis and eosinophilia improved with pancreatic stent placement.
