Xanthogranulomatous pancreatitis mimicking a malignant solid tumour

Xanthogranulomatous inflammation, which is known to occur in several viscera, is rarely found to affect the pancreas. We report a case of xanthogranulomatous pancreatitis (XGP) occurring in a 60-year-old man who presented with epigastric pain and vomiting. Physical examination did not reveal any abnormality. Contrastenhanced CT of the abdomen revealed an ill-defined, heterogeneous mass lesion in the uncinate process of the pancreas, suggestive of malignancy. Whipple's pancreaticoduodenectomy was performed and the final pathological diagnosis was XGP. The patient's postoperative course was uneventful. When a pancreatic mass does not show clinicoradiological features typical of common pancreatic neoplasms, XGP should be considered for a differential diagnosis and duodenum preserving surgery can be considered.
