Case Discussion
Schwannoma is a benign neural sheath tumor that exhibits Schwann cell differentiation. It is a slow growing tumour and recurrence is rare. Common sites include posterior spinal roots, head and neck regions, and flexors of extremities.
Microscopically, wavy spindle-shaped Schwann cells can be seen. Areas that appear dense and eosinophilic are called Antoni A regions, while the Antoni B regions correspond to the looser, hypocellular areas with myxoid component. Verocay bodies, areas that contain distinct palisading nuclei adjacent to nuclear-free zones, can also be observed in Antoni A regions.
