Light microscopic examination of the tumor cells. The tumors removed were processed and slides were washed and counterstained with H&E stain (200x), observed under light microscopy showing polygonal and oval in shape. The tumors were composed of sheets, nests and trabeculae of cells with distinct borders and containing moderate to abundant amounts of eosinophilic cytoplasm. The nuclei were oval and located in the center of the cells. The arrows indicate the tumor cells.
