[Cervical ganglioneuroma. Review, apropos of a case]

We describe a case of cervical ganglioneuroma, an uncommon benign tumor which develops slowly, predominantly in females and infants. Ganglioneuromas have a neuroectodermic origin and are localized along the sympathetic trunk. Most are unmasked fortuitously by palpation or by high serum catecholamine levels proportional to tumor size. After radiographic exploration and surgical excision, a pathologic study of the surgical specimen is required to identify this very differentiated tumor stemming from the neural crest.
