- Immunohistochemical staining may be helpful in the diagnosis of VIPoma. Findings suggestive of VIPoma include positive histochemical staining for:[1]

- Cytokeratin 19 positive stain is an independent marker of aggressive behavior in pancreatic neuroendocrine tumors.
- Synaptophysin
- Ki-67 (indicates the percentage of neoplastic cells immunolabeled for the marker of proliferation Ki67)
- NSE (neuron-specific enolase)
- PGP 9.5 (protein gene product 9.5)
