Figure 2: Histopathology examination of granular cell tumor by H and E. (a) Clusters and nests of tumor cells with abundant eosinophilic granular cytoplasm separating thick collagen bundles (H and E; 20x); (b) Large pink epithelioid type cells and bland nuclei containing granular eosinophilic cytoplasm, occasional intranuclear pseudoinclusion seen (H and E; 40x); (c) Immunohistochemistry showing strong diffuse positivity for S-100 (40x); (d) Benign GrCT show rare reactivity to Ki-67, <2% (40x)
