incipient IPMN

Incipient intraductal papillary mucinous neoplasms (IPMNs) are poorly described subcentimeter pancreatic cysts with papillae and mucin similar to IPMNs.

They are larger than pancreatic intraepithelial neoplasia but do not meet the cutoff size for IPMNs (≥ 1 cm).

Molecular biology

 GNAS codon 201 mutations are hallmark genetic alterations of IPMNs.
