IPMNs are potentially malignant intraductal epithelial neoplasms that are composed of mucin-producing columnar cells.
These lesions show cyst formation,
papillary proliferation and varying degrees of atypia.
IPMNs can be classified into three types,
Main duct (MD-IPMN),
branch duct (BD-IPMN),
and mixed type,
based on imaging studies and histology.
They were first described in the 1980's , the incidence rate and natural history of IPMN are not fully known. IPMN is being recognized with increasing frequency around the world and the number of pancreatic resections for IPMN is rising .
