Pathomorphological and immunohistochemical diagnostics of glioblastoma with pseudoepitelial differentiation
The article describes a glioblastoma with signs of pseudoepithelial differentiation in a 53-year-old woman. This case is of great practical interest due to the rare occurrence of such pathology. Each neurosurgeon, oncologist, or pathologist should be familiar with glioblastoma with signs of pseudo- and true epithelial differentiation, simulating morphologically metastatic carcinoma. Immunohistochemistry in combination with preoperative visualization are fundamental methods of diagnostics.
