Description

Background : Autoimmune pancreatitis (AIP) is an inflammatory disorder causing a mass that is often operated on as pancreatic cancer. We report such a case.<br>Case : A 67-year-old man reporting had dysgeusia and brown urine had intrahepatic bile duct dilation pointed out on computed tomography and obstructive jaundice diagnose due to a tumor. Cytology of the bile showed small, irregularly arranged clusters against the bile pigment background. Cells forming clusters showed irregular nuclei and mildly increased of fine granule-shaped chromatin. Histologically, the lesion showed fibrosis between the pancreatic duct and pancreatic lobule, with distinct lymphatic infiltration and IgG4-positive plasma cells.<br>Conclusion : AIP which is an inflammatory disorder. Steroid therapy is very effective in treating. An accurate diagnosis is thus needed to avoid surgical excision. Confirmation by EUS-FNA cytology may be necessary when we must refer the clinical background and conduct a serological investigation.
