Chondrodermatitis Nodularis Helicis

Key Points

  • Chondrodermatitis nodularis helicis (CNH) is an uncommon painful lesion on the helix or antihelix of the ear that often appears as a crusted ulceration mimicking a cutaneous malignancy. It is extremely rare in children. It etiology is unclear but thought to be due to repetitive micro trauma, especially pressure, to the area in susceptible individuals.
  • Diagnosis may be made by clinical exam and the symptom of pain, but biopsy is commonly performed to exclude cutaneous malignancies.
  • Treatment aimed at protecting the area with local measures is usually effective. For refractory cases, there are a number of topical, intralesional, and ultimately surgical treatment approaches.
