Abstract:
Oncocytic meningioma is a recently described rare variant of meningothelial neoplasms that typically occurs as a large cell tumor with granular cytoplasm. The distinct histological features of numerous cells with granular cytoplasm and the ultrastructural evidence of numerous mitochondria in the cytoplasm differentiate this tumor from other neoplasms with granular appearance. We report an additional case of oncocytic meningioma investigated by ultrastructural and immunohistochemical methods.
