Images show a Schwannian stroma dominant ganglioneuroma, maturing subtype, with favorable histology. This tumor likely represents a biologically favorable neuroblastoma that metastasized to the lymph nodes early in the clinical course and subsequently showed ganglioneuromatous maturation. a Hematoxylin and eosin (H&E) stain at 20× magnification showing a Schwannian stroma dominant tumor with mature ganglion cells with abundant dense eosinophilic cytoplasm, eccentric nuclei, and prominent nucleoli. b H&E stain at 40× magnification showing Schwannian stroma dominant tumor with mature ganglion cells with abundant dense eosinophilic cytoplasm, eccentric nuclei, and prominent nucleoli. c S100 immunohistochemical stain at 100× magnification showing strong positive staining within the Schwannian stroma dominant tumor. d H&E stain at 40× magnification showing ganglioneuroma metastatic to a lymph node
