[Schwannoma of the cervical sympathetic chain]

Schwannomas are benign tumors of neural source produced from Schwann cells, which are the constituents and the maintenance of myelin sheath of peripheral nerves. Parapharyngeal schwannoma are sporadic and vagus nerve the one more frequently giving raise to parapharyngeal schwannoma. Those originated in sympathetic neck chain are more rare. We inform about a parapharyngeal schwannoma case of the neck sympathetic chain and perform an analyse of clinic, diagnostical, histological and therapeutical characteristics of this so infrequent pathology.
