Abstract
The current World Health Organization (WHO) classification of central nervous system (CNS) tumours includes several neoplasms that, while occurring in this location, are more frequently seen extracranially. These include mesenchymal, melanocytic and haematolymphoid neoplasms, as well as metastases. A few of these entities are exclusive of the CNS and have no extracranial counterpart. Despite their diverse histogenesis, these neoplasms share a peculiar predilection for involving meningeal structures. In fact, in the context of an intraoperative pathologic consultation of a meningeal tumour, virtually all these entities should be considered as potential diagnoses. Metastases in the CNS are very common. Most are carcinomas that cytologically resemble their site of origin. Loss of differentiation with cell dissociation and anaplasia and presence of accompanying fibrillary brain parenchyma can be a source of diagnostic problems. In this review, we intend to show the most relevant cytologic features of these tumours, and it is especially aimed at their analysis during intraoperative studies.
