Examination of specific markers expression of ganglioneuroblastoma (case 1). A) Hematoxylin and eosin staining of the tumor sample (HE; 200x). B) NB84 expression in the tumor (immunohistochemistry NB84; 400x). C) Protein S100 immunoreactivity on the cells of the tumor (in this case ganglioneuroblastoma, S100; 400x). D) CD56 also called neural cell adhesion molecule (NCAM) immunoreactivity on the ganglioneuroblastoma cells (CD56; 200x). E) Positive expression of neuron specific enolase in the tumor sample (NSE) (NSE; 200x). F) PGP9.5 expression in the tumor sample (PGP9.5; 200x)
