While intradermal nevi are common benign pigmented skin tumor, occurrence within the external auditory canal is uncommon. We experienced two cases of intradermal nevus which originated in posterior wall of external auditory canal. They were treated by en block excision with split thickness skin graft. The clinical and pathologic features of the intradermal nevus arising within the external auditory canal are presented, and the literatures were reviewed. (J Clinical Otolaryngol 2005;16:289-292)
