[Dermoid cyst presenting with atypical upper extremity neurological symptoms]

Abstract

Dermoid cysts, also known as teratodermoids, are benign tumours thought to originate from multipotent embryonic cells which constitute approx. 10% of all mediastinal tumours. This is a rare presentation of a mediastinal cystic teratoma presenting with radiating pain and disturbed sensitivity in the right upper extremity. These tumours are generally benign and surgery is the treatment of choice.
