What is Which of the following malignancy shows rosette shaped arrangement of cells in histology? and explain in detail?
Ependymomas are derived from ependymal cells, i.e., the cells lining the ventricles of the brain and the central canal of the spinal cord; this is the most common glioma of the spinal cord. These cells have both glial and epithelial characteristics. The most common cerebral site is the fouh ventricle; less often they occur in the lateral or third ventricles. The tumor cells tend to form rosettes with central lumens or, more often, circular arrangements around blood vessels (pseudorosettes). Ref: Ropper A.H., Samuels M.A. (2009). Chapter 31.
