Tumour cells are immunoreactive to chromogranin, synaptophysin and insulin (3f, 3g, 3h × 400 each). MIB 1 LI is 2% (d3i × 200). Electron micrographs showing numerous membrane bound electron dense neurosecretory granules, mitochondria and prominent rough endoplasmic reticulum (3j × 2550; 3k × 9000 original magnification).
