Rhabdoid meningioma lacking malignant features: Report of a rare case with review of literature

We reported a case of meningioma with rhabdoid morphology but lacking histological features of malignancy in arising from the spinal cord in a 28-year-old male. The tumor showed light microscopic, immunohistochemical evidence of meningothelial differentiation together with diffuse areas exhibiting rhabdoid morphology. The rhabdoid areas were characterized by cells with large cytoplasmic eosinophilic inclusions and eccentric nuclei. Unlike most cases reported in the literature, this case lacked significant mitotic activity and other atypical features. The diagnostic and prognostic significance of this tumor entity is discussed along with a review of the literature.
