The value of electron microscopy in differentiating central nervous system neoplasms showing mucous secretion is stressed.

The association of central nervous system neoplasms in neurofibromatosis is common and children are at particular risk.

We review the current classification of the central nervous system neoplasms focusing on grading and new clinicopathological entities.

Radiation therapy plays a critical role in the treatment of central nervous system neoplasms and cerebral arteriovenous malformations.

Both ocular and central nervous system neoplasms are heritable in heterozygous offspring through 10 sequential generations of breeding.

The light and electron microscopic characteristics as well as immunocytochemical features of undifferentiated midline central nervous system neoplasms further correlate with human trilateral retinoblastoma.
