Definitions for ganglioneuroblastoma
Ganglioneuroblastoma is a variant of neuroblastoma that is surrounded by ganglion cells. It can be difficult to diagnose. Nodular ganglioneuroblastoma can be divided by prognosis.
U.S. National Library of Medicine
A moderately malignant neoplasm composed of primitive neuroectodermal cells dispersed in myxomatous or fibrous stroma intermixed with mature ganglion cells. It may undergo transformation into a neuroblastoma. It arises from the sympathetic trunk or less frequently from the adrenal medulla, cerebral cortex, and other locations. Cervical ganglioneuroblastomas may be associated with HORNER SYNDROME and the tumor may occasionally secrete vasoactive intestinal peptide, resulting in chronic diarrhea.
