MUC1 and Meningothelial Meningioma: Meningothelial meningioma is typified by meningothelial whorls, syncytial cells with round uniform nuclei, intranuclear pseudoinclusions, and immunohistochemical staining for markers like somatostatin receptor 2a (SSTR2A), epithelial membrane antigen (EMA), and vimentin and progesterone receptors [58].
