title: Pineocytoma. Observation of an autopsy case by electron microscopy and cell markers.
abstract: 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.
