Figure 3. Histopathological and immunohistochemical findings.

Figure 3

A. H&E stained section of case 1 showed sheets of isomorphic tumor cells with round nuclei and clear cytoplasm, and large lipid vacuoles among neoplastic cells. B. H&E stained section of case 2 showed sheets of relatively monomorphic tumor cells, neuropil among small tumor cells and some cells containing large intracytoplasmic vacuoles. C. Tumor cells were diffuse positivity for synaptophysin in case 1. D. Strong labeling was seen with S-100 in tumor cells, lipidized cells and glial cells in case 1. E. Tumor cells were moderately positive for NeuN in case 2. F. GFAP was largely negative on tumor cells in case 1. (original magnification × 200)
