[Benign cervical tumors of neuroectodermal origin: apropos of 3 clinical cases].

Neuroectoblastic benign cervical tumors. Report of three clinical cases. Cervical neurogenic tumors are uncommon. They arise from the cranial nerves, the cervical sympathetic chain and the paraganglion cells of the parasympathetic system (non chromaffin cells). Three cases are reported (schwannoma-ganglioneuroma-chemodectoma). The pertinent literature is reviewed for the classification, the diagnosis and the treatment.
