Definition

Ganglioneuroma is a benign and differentiated tumor of sympathetic ganglia containing maturing or mature ganglion cells and nerve fibers and is without immature neuroblastic component, occurring most commonly in posterior mediastinum. It is the most differentiated tumor in neuroblastic tumors (neuroblastomas), which are composed of cells with different degrees of differentiation, from immature neuroblastomas, over more mature ganglioneuroblastomas, to mature ganglioneuromas. Their malignant potential correlates with the amount of immature cells. In most cases ganglioneuroma arises de novo, but can develop by maturation of neuroblastoma. In half of the patients, they are symptomatic, and in one third there might be calcifications on CT scan. However, levels of catecholamine metabolites in urine are usually normal, unless there is a large tumor mass, when they can be elevated.

Clinical Features

    Ganglioneuromas are rare if compared to benign neurogenic tumors like...
