PPoma can be associated with multiple endocrine neoplasia 1 (MEN-1)."

They can be functional, exhibiting a hormonal hypersecretion syndrome, but can be non-functional presenting with non-specific symptoms and include insulinoma, glucagonoma, VIPoma, somatostatinoma (SSoma), PPoma and Zollinger-Ellison syndrome (ZES, or gastrinoma) and other ectopic hormone producing tumors (such as GRFoma)."
