Ganglioneuroma - Stroma Dominant
Tumors in this category are predominantly composed of ganglioneuromatous stroma with a minor component of scattered neuroblastic/ganglionic cells. There are no microscopically distinct neuroblastomatous foci. Schwannian stroma has a well-organized appearance of fascicular formation.
Tumor in the maturing subtype contains evenly or unevenly distributed differentiating neuroblasts and/or maturing ganglion cells, in addition to fully mature ganglion cells.
Tumor in the mature subtype contains fully mature ganglion cells which are usually surrounded by satellite cells.
