Autoimmune pancreatitis is a rare condition, accounting for less than 5% of chronic pancreatitis, characterized by clinical, histopathological, radiographic, serologic, and therapeutic features. This benign disease resembles a pancreatic tumor both clinically and radiographically. We report the case of a 53-year-old man with no history who presented cholestatic jaundice and an image suggestive of the pancreatic tumor. A cephalic duodenopancreatectomy (Whipple's operation) was performed and an anatomopathological examination of the operative specimen confirmed that it was type II autoimmune pancreatitis. The evolution was marked by the remission of clinical and biological signs. Accurate and timely diagnosis of autoimmune pancreatitis is particularly important because steroid therapy is effective and pancreatic resection is not necessary.
