Fig. 3

Pathologic specimens of intraorbital granular cell tumor. Histology shows a fibrotic soft tissue infiltrates with nests of polygonal tumor cells; b involvement of nerves around the tumor is also noted (hematoxylin and eosin stain, original magnification ×100); and c abundant eosinophilic granular cytoplasm and small nuclei. There is no cytologic atypia, increased mitotic activity, or necrosis (hematoxylin and eosin, ×200). Immunohistochemical stains for d S100, e CD68, and f MIB-1. The granular cells are diffusely positive for S100 (×400), and focally positive for CD68 (×200). The MIB-1 labeling index is 3, which represents low proliferation (×200)
