Sections of pancreas tissue showed an islet cell tumor and surrounding adjacent IPMH. The islet cell tumor grew in a nodular pattern and was surrounded by fibrotic stroma.
In the present report, the IPMH and islet cell tumors were topographically separated, but the islet cell tumor had a ductule component.
Although the intraductal papillary mucinous changes (the IPMHs) in the present case do not meet the diagnostic criteria of IPMT because of the lack of dilatation of the main pancreatic ducts, the IPMH may represent an early stage or a precursor lesion of IPMT.
