Biological and Demographic Profile of Meningiomas in a Cohort of Egyptian Patients: Impact on Tumor Recurrence
Figure 1
(a) Bone invasive meningioma: an island of meningioma tissue with numerous psammoma bodies is seen invading lamellar bone trabeculae (H&E, 100x); (b) brain invasive meningioma: tongues of meningioma tissue invading brain parenchyma are noted (H&E, 40x); (c) secretory meningioma: PAS histochemical stain is highlighting the intracytoplasmic inclusions characteristic of this subtype (PAS, 100x); (d) reticulin fibers are surrounding syncytial groups of meningioma cells (reticulin, 200x).
