Chondrodermatitis nodularis helicis (Winkler)

• Chondrodermatitis nodularis helicis

• Chondrodermatitis nodularis chronica helicis

• Winkler disease

• Chondrodermatitis nodularis antihelicis

Benign, chronic inflammatory, pressure-painful lesion of the auricle, usually located on the helix and less commonly on the antihelix. Typically, it presents as a solitary, firm nodule a few millimeters in size or as a papulonodular lesion with a central crust, erosion, or ulceration. The cardinal symptom is marked localized tenderness to pressure, often especially at night when lying on the affected ear.

The condition primarily affects older adults and is more common in men than in women. Children are affected only exceptionally. A reliable population-based incidence has not been established.

Chronic inflammatory, non-malignant disease of the auricle.

The pathogenesis has not been fully clarified. The most plausible explanation is local pressure-induced ischemia in the setting of anatomically minimal soft tissue coverage over the auricular cartilage.

Probable predisposing factors

• repeated pressure, especially due to sleeping position

• chronic mechanical irritation, for example from spectacle frames, headphones, headsets, helmets, or hearing aids

• local hypoperfusion of the skin-cartilage area

• possibly additional actinic pre-damage or cold exposure

For clinical practice, the key point is: persistent local pressure is the most important modifiable factor.

Typically, there is a single painful papule or small nodule on the helix or antihelix, usually measuring 4–10 mm.

Key clinical features

• marked localized tenderness to pressure

• worsening pain when lying on the affected ear

• central crust, erosion, or small ulceration

• firm consistency, sharply demarcated lesion

• surrounding erythema may be present

Pain is often clearly disproportionate to the size of the lesion. Pruritus is not a leading symptom. Exudation or slight bleeding may occur after manipulation or detachment of the crust.

The diagnosis is usually clinical.

Typical constellation

• solitary painful lesion

• typical location on the helix or antihelix

• chronic course

• pronounced pressure pain, often with sleep disturbance

Dermoscopy

May be supportive. Described findings include a central crust or ulceration with peripheral vascular structures on an erythematous or whitish fibrotic background. Dermoscopy does not replace histology when the biological nature of the lesion is uncertain.

When to biopsy?

• atypical morphology

• absence of pain

• rapid growth

• marked hyperkeratosis

• pigmentation

• recurrent or treatment-resistant lesion

• any clinical suspicion of squamous cell carcinoma, basal cell carcinoma, or another neoplasm

Laboratory investigations are generally not required.

Almost always on the auricle.

Typical sites

• helix, especially the upper or lateral rim

• less commonly the antihelix

  
  
  

In most cases, the lesion is unilateral and solitary.

• localized ear pain present for weeks to months

• pain especially at night or when sleeping on one side

• patient avoids lying on the affected side

• often recollection of chronic pressure or friction

• no systemic symptoms

A practically useful direct question is: “Does it hurt when you sleep on this ear?”

Histology is not highly specific, but serves primarily to exclude malignant differential diagnoses.

Typical findings

• epidermal hyperkeratosis, often with parakeratosis

• central erosion or ulceration

• acanthosis or pseudoepitheliomatous hyperplasia may be present

• inflammatory infiltrate in the dermis

• degenerative changes in the collagenous connective tissue

• frequent signs of perichondritis; cartilage involvement may be present

The decisive point is the absence of a malignant epithelial tumor.

• chronic pain

• sleep disturbance

• persistence over months

• recurrence if pressure persists

• scarring after interventional or surgical treatment

• rarely, secondary bacterial superinfection of ulcerated lesions

Benign, but often persistent. With consistent pressure relief and appropriate therapy, symptom improvement is frequently achievable. Recurrences are possible, especially if pressure reduction is inadequate or the pressure-exposed cartilage area is not completely addressed.

The most important preventive measure is consistent pressure relief of the auricle.

Practical measures

• change sleeping position

• use a pillow with a cut-out or a donut/ear pillow

• reduce pressure from spectacle frames, headsets, helmets, or hearing aids

• avoid local friction

• consider ear protection in cold exposure

The therapeutic goal is freedom from pain while simultaneously relieving pressure and excluding a malignant process.

First-line: conservative pressure relief

Consistent pressure reduction is the most important initial measure and should almost always be part of treatment.

Proven practical measures

• donut pillow or pillow with an ear cut-out for nighttime use

• foam, silicone, or felt padding for local offloading

• adjustment of spectacles, headset, helmet, or hearing aid

In many patients, pain and inflammation improve significantly with consistent offloading alone.

Topical and intralesional options

These methods may be used as adjunctive treatment, especially for small lesions or when surgery is to be avoided.

Possible options

• topical corticosteroids: may reduce inflammation and irritation, but are often insufficient as monotherapy

• topical nitroglycerin: described as a vasodilatory approach; may be effective, but practical use is limited by possible headache and local irritation

• intralesional triamcinolone: may be attempted, although success rates are variable and recurrences are not uncommon

Evidence for diltiazem and other local treatments is limited; they are not standard therapy.

Other non-surgical procedures

Cryotherapy, laser-based procedures, or photodynamic therapy have been described, but mostly only in small series or case reports. They are more suitable in selected situations when conservative measures are insufficient and surgery is to be avoided.

Surgical therapy

In cases of persistent pain, recurrence, unclear diagnosis, or failed conservative treatment, surgery is a very good option.

Principles

• excision of the lesion

• concomitant treatment of the underlying pressure-exposed or altered cartilage segment

• careful smoothing of remaining cartilage edges

Common procedures

• skin and cartilage excision

• skin-sparing excision with cartilage resection

• depending on defect size, primary closure or local reconstruction

The specific technique depends on location, defect size, and cosmetic requirements. For recurrence prevention, the key is not only removal of the visible lesion, but also elimination of the mechanically problematic cartilage area.

Practical notes and pitfalls

• Before destructive treatment, always consider squamous cell carcinoma and basal cell carcinoma.

• In atypical, hyperkeratotic, pigmented, or rapidly growing lesions, histologic confirmation should be obtained first.

• Without consistent pressure relief, both conservative and surgical procedures carry a risk of recurrence.

• Pain is often the leading symptom; a small lesion may be highly clinically relevant.
