“…16 The tumor generally arises in the cerebral hemispheres and seems to have a predilection for the periventricular region of the temporal lobe (38% of cases). 12,16 Imaging studies show a welldemarcated, contrast-enhancing solid and cystic tumor which demonstrates little mass effect. Most cases are asymptomatic, but some patients present with focal neural deficits, headaches, and seizures.…”

Three new entities have been recently added to the group of glioneuronal tumors in the most recent update of the World Health Organization classification of tumors of the central nervous system: papillary glioneuronal tumor, rosetted glioneuronal tumor with neuropil-like islands, and rosette-forming glioneuronal tumor of the fourth ventricle. These tumors are relatively infrequent lesions, and because of that, they can be challenging to diagnose for the practicing pathologist. In this article, we summarize the clinical and pathologic findings of these new lesions.

“…(1) included the term "cerebellar liponeurocytom a " . H o w e v e r , T h i s t e r m i s n o w w i d e l y accepted, and is supported by genetic analyses indicating that this lesion is not a variant of medulloblastoma (170). Clinical, histopathological, immunohistochemical, and genetic data strongly suggest that the cerebellar liponeurocytoma comprise a rare but distinct clinicopathological entity.…”

“…Calcification may or may not be found. [2][3][4][5][6][7][8] On histology, these tumours characteristically show two different components, namely glial and neuronal as the name itself implies. The neuronal component shows a spectrum that includes mature neurocytes, ganglioid cells and ganglion cells, all staining with neuronal markers such as synaptophysin in a neuropil-rich background.…”

Usefulness of smears in intra‐operative diagnosis of newly described entities of CNS

The recent edition of World Health Organisation (WHO) Classification of Tumours of the Central Nervous System has incorporated a substantial number of important changes. It has recognised several new entities, many of which are rare. Intra-operative diagnosis of these tumours can be difficult with the freezing artefact that often cripples brain frozen sections. In many instances intra-operative smears are extremely useful adjuvants in neuropathological diagnosis. In this article, we describe intra-operative smear findings of three of the newly described tumours. Their characteristic cytologic features are illustrated along with differentiating features from the common mimics, together with a general approach to brain smears. The entities we discuss here are papillary glioneuronal tumour, papillary tumour of the pineal region and angiocentric glioma. All three tumours share at least focal pseudo-papillary/vasculocentric architecture. Smears from papillary glioneuronal tumour demonstrated dual population of cells in a neuropil background, whereas papillary tumour of the pineal region and angiocentric glioma comprise a single population of cells. These two tumours can further be differentiated based on their cell morphology and background.
