Nevus Sebaceous of External Auditory Canal; Significance of Managing It: A Rare Case Report

Abstract

Introduction: Nevus sebaceous is a benign mass lesion occurring primarily on the face, scalp, and periauricular region. The occurrence of this lesion in the external auditory canal is very rare. Case description: We present a case of nevus sebaceous of the external auditory canal, which was diagnosed with the help of histopathology and treated successfully by surgical excision. Discussion: The nevus sebaceous is a benign lesion but harbors malignant potential in it, necessitating excision of the lesion with adequate margins in order to avoid recurrence or malignant transformation. Conclusion: Nevus sebaceous although rare but can arise in the external ear canal and can be managed successfully if excised completely with adequate margins.
