The lesion was stained positive for CD56, chromogranin, and creatine and negative for S100 and vimentin in immunohistochemical staining (Figures 1, 2, 3, and 4).
Observed structures, all of which were of tumoral quality. Patchy vascular structures were apparent. Frequent mitotic activities were present. Tumor cells consisted of atypical cells with uniform nuclei and narrow cytoplasm, and some with vesicular nuclei. Immunohistochemical studies showed a positive staining with CD56.
