Classification

The 2007 WHO classification of central nervous system tumors divides pineal gland tumors into four groups:

  • Pineocytoma (grade I)
  • Pineal parenchymal tumors of intermediate differentiation (grade II or III)
  • Papillary tumor of the pineal region (grade II or III)
  • Pineoblastoma (grade IV)

According to the WHO classification of tumors of the central nervous system, pineocytoma is classified into a WHO grade I tumor.[1]
