Abstract
Most pineal-region neoplasms are germ cell tumors, followed by PPTs and gliomas. Given its axial deep-seated localization, stereotactic biopsy is the method of choice for obtaining diagnostic tissue. Cytologic features of PPT are quite different. Pineoblastoma shows an undifferentiated appearance similar to that of embryonal tumors, whereas pineocytoma resembles central neurocytoma with round, uniform pineocytic cells.
