Summary

Chondrodermatitis nodularis helicis (CNH) is a benign, painful, inflammatory condition of the external ear characterized by a solitary, hyperkeratotic, central-crusted nodule primarily affecting the helix or antihelix. We present a case of CNH clinically mimicking basal cell carcinoma, which was successfully identified and definitively cleared using Mohs micrographic surgery, resulting in immediate symptomatic relief and an optimal aesthetic outcome.
