From: Recurrent orbital schwannomas: clinical course and histopathologic correlation
Case 1. Orbital schwannomatosis. A: Histopathology of first tumor excision (H&E and IHC) revealing S-100 positivity (inset), indicating schwannoma. Original magnification 200x. B: Magnetic resonance imaging of the recurrent tumor demonstrating two distinct well-circumscribed superior orbital lesions (arrows) with patchy enhancement on T1 (B) and T2 (B’) imaging. C: Intraoperative photo of excised mass. D: Gross pathology of excised mass, with window in capsule showing contents. E: Histopathology of recurrent lesion (H&E) revealing schwannoma. Original magnificantion 100x and 400x (inset).
