Nodular Ganglio-neuroblastoma

Nodular ganglioneuroblastomas are composite tumors that have a well-defined highly cellular area of neuroblastoma (seen grossly as a variegated red-brown nodule in this image) in a background of a ganglioneuroma.

The Schwannian stroma-rich/stroma-dominant areas (ganglioneuroma component) are sharply demarcated from the stroma-poor zones (neuroblastoma component). Image courtesy of Dr. Jean-Christophe Fournet, Paris, France; humpath.com; Used with permission
