Ganglioneuroma of the mandible: radiologic and pathologic findings of a rare tumor.

Ganglioneuroma is a rare benign neural tumor, thought to arise from the ganglia of the sympathetic chain or parasympathetic nervous system. It is therefore most commonly seen in the abdomen and thorax. The occurrence of ganglioneuroma in the mandible is exceptional; to date only 5 cases have been reported. We present another case of ganglioneuroma of the mandible, demonstrate the radiologic and pathologic findings, and discuss the possible causes of the tumor at this site.
