Histopathological and immunostained microphotographs of our case of granular cell tumor. (A) Low-power microphotograph exhibiting that the tumor was covered by slightly hyperplastic parakeratinized stratified squamous epithelium (Hematoxylin and eosin stain or H&E; original magnification, 4×). (B and C) Medium- and high-power microphotographs demonstrating sheets or nests of large, polygonal tumor cells with abundant slightly basophilic and granular cytoplasm and vesicular nuclei infiltrating among skeletal muscle fibers. The cell borders were indistinct and some cells seemed to fuse together to show a syncytial appearance (C) (H&E; original magnification; B, 20×; C, 40×). (D) Immunostained microphotograph showing that the tumor granular cells were positive for S-100 protein. (Immunostain; original magnification, 20×).
