1 A, Recurrent neoplasm in patient 6.
A, Recurrent neoplasm in patient 6. Photomicrograph (hematoxylin-eosin stain; original magnification, X120) shows the lesion was a pleomorphic, hypercellular astrocytic neoplasm (arrow) with areas of tumor necrosis and prominent endothelial proliferation.B, Histology of treatment effects in patient 13. Photomicrograph (Hematoxylin-eosin stain; original magnification, X120) of biopsy specimen in this patient from the nonrecurrence group shows reactive gliosis and radiation changes, with necrosis of nonneoplastic brain.
