Figure 1: Histopathological evaluation of the excised skin nodule from the back. H and E, ×100 shows tumor cells arranged in sheets and ill-formed lobules infiltrating skeletal muscle bundles (a) and show stippled chromatin (b). Tumor cells highlighted by Chromogranin stain, ×200 (c). Section shows lymphovascular invasion by tumor cells adherent to the endothelium H and E, ×200 (d). They also exhibit strong diffuse cytoplasmic staining for synaptophysin stain, DAKO antibody USA, ×400 (e)
