Chondrodermatitis Nodularis Chronica Helicis

CNCH (Ear Nodule)

Overview

Chondrodermatitis nodularis chronica helicis (CNCH) is a benign but painful inflammatory condition that produces a small, tender nodule on the helix or antihelix of the ear. It is thought to result from chronic pressure (such as sleeping on one side), sun damage, or cold exposure leading to localized ischemia and degeneration of the ear cartilage. It is most common in men over 40.

Key Symptoms

  • Small (3-10 mm), firm, very tender nodule on the ear
  • Located on the helix (men) or antihelix (women) most commonly
  • Skin-colored, pink, or red with possible central crust or scale
  • Exquisitely painful, especially when lying on the affected side
  • Pain often disrupts sleep due to pressure on the ear
  • May have a small central ulcer or channel draining to the cartilage

Affected Areas

Helix of the ear, Antihelix of the ear

Care Instructions

  1. Relieve pressure on the ear by using a donut-shaped pillow or ear protector when sleeping.
  2. Topical or intralesional corticosteroids may reduce inflammation and pain.
  3. Cryotherapy can be tried for small lesions.
  4. Surgical excision with removal of the underlying damaged cartilage is the most definitive treatment.
  5. Protect the ears from cold exposure and sun damage.
  6. See a dermatologist to confirm the diagnosis and discuss treatment options.
