ABSTRACT

The pineal gland primary neoplasms originated or in its vicinity are classified as tumors of the parenchyma, interstitium or tumors of germinal origin. The WHO classification of central nervous system tumors divides the parenchyma tumors in pineocytomas, pineoblastomas and mixed ones (pineocytoma-pineoblastoma). These tumors are clinicopathologic entities that vary from well differentiated (pineocytomas) to poorly differentiated (pineoblastomas). The cytopathological findings of two cases of pinealoblastoma diagnosed on material obtained by stereotaxic biopsy are presented.
