Pancreatic intraepithelial neoplasia (PanIN) is one of the most important issues for the early detection of pancreatic ductal adenocarcinoma. In particular, PanIN-3 is recognized as a precancerous lesion, e.g., carcinoma in situ, high-grade dysplasia, and severe dysplasia. We report a rare, completely resected case of PanIN-3 in the main pancreatic duct (MPD) detected from localized pancreatitis. A 63-year-old man developed upper abdominal pain with hyperamylasemia. He underwent distal pancreatectomy soon after recovery because an abnormal narrow segment, suggesting PanIN, was identified in the pancreatic body by endoscopic retrograde cholangiopancreatography. Histopathological findings revealed a PanIN-3 located in the MPD that could be resected completely. This finding suggests that if unidentified localized pancreatitis develops, we should carefully examine the fine structural changes in the MPD.

Pancreatic intraepithelial neoplasia (PanIN) is considered a pre-malignant lesion difficult to identify by imaging methods. EUSFNA is an effective technique to obtain material for histopathological study of pancreatic cystic tumors, but it is not free of adverse events. We report a case of a 56 years old patient, with chronic abdominal pain (early 1994). MRI showed pancreatic cystic images. The etiologic diagnosis was doubtful and EUS-FNA was performed. Immediately after a FNA, patient had an episode of acute pancreatitis, requiring hospitalization. During one year after FNA he had five episodes of AP. A new EUS suspected of PanIN, which was confirmed by surgery. After surgery the patient is well and has no more episodes of AP. Although the risk of AP, EUS-FNA should be performed to determine the best treatment for these patients with chronic abdominal pain who have cystic changes of pancreatic gland.
