Cytopathology of glioneuronal and neuronal tumours with histological correlations

Cytopathology, Volume 35, Issue 5, Page 545-555, September 2024.
Abstract Glioneuronal and neuronal tumours constitute a diverse group of tumours that feature neuronal differentiation. In mixed glioneuronal tumours, a glial component is present in addition to the neuronal component. With a few exceptions (eg diffuse leptomeningeal glioneuronal tumour) they are well‐circumscribed and slow‐growing tumours, which is ...

Cytological features of ependymal and choroid plexus tumours

Cytopathology, Volume 35, Issue 5, Page 556-560, September 2024.
The authors review and illustrate cytological features of conventional ependymomas, subependymomas and myxopapillary ependymomas as well as choroid plexus tumours. Abstract Ependymal and choroid plexus tumours arise in anatomically related regions. Their intraoperative differential diagnosis is large and depends on factors such as age, tumour site and ...

Unique case of atypical central neurocytoma with craniospinal metastases and pituitary adenoma

Asian Journal of Neurosurgery, 2020
Atypical central neurocytoma with extracranial metastases is a rare variant of benign central neurocytoma (CN). No definitive course of treatment exists for atypical CN. We report a unique case of atypical CN with concomitant pituitary macroadenoma and subsequent metastases to the spine. The patient received craniospinal radiation therapy. Close-follow

A retrospective analysis of practical benefits and caveats of the new WHO 2021 central nervous system tumor classification scheme in low‐resource settings: “A perspective from low‐ and middle‐income countries”

Neuropathology, Volume 44, Issue 3, Page 183-189, June 2024.
The revised classification of tumors of the central nervous system (CNS) by the World Health Organization (WHO) in 2021 was hailed as a major advance and improvement in the management of brain tumor patients. However, the increased reliance on sophisticated technology and molecular analysis posed a major challenge to healthcare systems in low‐ and ...

Utility of combining OLIG2 and SOX10 IHC expression in CNS tumours: promising biomarkers for subtyping paediatric‐ and adult‐type gliomas

Histopathology, Volume 84, Issue 5, Page 893-899, April 2024.
Aims The SOX10 transcription factor is important for the maturation of oligodendrocytes involved in central nervous system (CNS) myelination. Currently, very little information exists about its expression and potential use in CNS tumour diagnoses. The aim of our study was to characterize the expression of SOX10 in a large cohort of CNS tumours and to ...
