What is chondrodermatitis nodularis helicis?
Chondrodermatitis nodularis helicis (CDNH) simply means inflamed cartilage and skin forming a tender lump on the ear. The tender scaly lump develops most often on the most protuberant part of the ear where pressure is applied.
Who gets chondrodermatitis nodularis helicis?
CDNH is more commonly observed in middle-aged males with fair skin, with 10–35% of cases reported in women. Incidences in children are rarely documented. 1
What causes chondrodermatitis nodularis helicis?
The cause of CDNH remains unknown, but several factors may contribute to its development, including:
- Sleeping on a firm pillow
- Exposure to cold and sun
- Trauma from wearing ill-fitting headphones or earmuffs that press on the involved area
- Connective tissue disease
What does chondrodermatitis nodularis helicis look like?
Initially there is a tender scaly area which may be flat or slightly raised. As the condition worsens, larger nodules develop and these may ulcerate.
How is chondrodermatitis nodularis helicis diagnosed?
The condition is usually diagnosed clinically. In some cases, a biopsy may be necessary to confirm the diagnosis.
How is chondrodermatitis nodularis helicis treated?
Treatment options will vary depending on the individual and their needs.
The aim of CDNH treatment is to prevent further pressure to the tender areas.
General measures include:
- Avoid sleeping on the affected side if possible.
- Choose a doughnut-shaped pillow. Use sun protective measures to prevent further damage.
Other treatment options may include:
- Topical corticosteroids
- Intralesional steroid injection
- Cryotherapy
- Surgical removal (excision)
What is the likely outcome of chondrodermatitis nodularis helicis?
CDNH usually resolves within a few months, but may recur. If cases are left untreated, the condition tends to wax and wane.
