Nesidioblastosis may be found on a partial pancreatectomy specimens taken for a suspected Insulinoma , and may be inapparent  macroscopically.

Some insulinomas are very small and the entire specimen may need to be embedded in order to find the tumour.

- Pattern of growth: trabecular, moire silk, packeted, diffuse;

- Immunostaining characteristics ;

- Appearance of islets away from the tumour :  hyperplasia, amyloid deposition.
