Ganglioneuroma
Diagnosis in short

Adrenal Ganglioneuroma. H&E stain.
LM ganglion cells (large cells with large nucleus and prominent nucleolus), disordered fibrinous-like material, eosinophilic granular bodies
LM DDx ganglioneuroblastoma
IHC synaptophysin +ve, S-100 +ve
Gross solid, firm, white
Site usually adrenal or retroperitoneal, paraspinal
Prevalence uncommon
Prognosis good

Ganglioneuroma is a benign neuroblasic tumour. It is also known as ganglioma.[1]

It should not to be confused with ganglioglioma.

Features:

  • Ganglion cells - key feature.
    • Large cells with large nucleus.
      • Prominent nucleolus.
  • Disordered fibrinous-like material.
