Pineocytoma Observation of an Autopsy Case by Electron Microscopy and Cell Markers

摘要

An autopsy case of a 69−year‐old female with pineocytoma was reported. The tumor showed neuronal differentiations, which were confirmed not only by light microscopy and electron microscopy, but also by a cell marker of neuron‐specific enolase. In addition, existence of astrocytes in the tumor which distributed sparsely was ascertained by electron microscopy and cell markers such as S−100 protein and glial fibrillary acidic protein.
