Medically reviewed by Dr. Anand S. Urhekar, MD, MD Pathology, Clinical Advisor · Last updated July 2026
An inherited (autosomal dominant) skin disorder caused by ATP2A2 gene mutations, producing greasy, crusted, warty brown papules in seborrhoeic areas and body folds, characteristic V-shaped notches at the free nail edge, and white papules inside the mouth. Heat, sweat, sunlight and friction trigger flares.

Quick Answer
Darier disease is an inherited condition producing greasy, crusted, warty brown papules on the chest, back, neck and skin folds, often with an unpleasant odour, plus red and white nail streaks ending in a V-shaped notch. Heat, sweat, sun and friction trigger flares. Treatment includes cooling, emollients, topical retinoids and corticosteroids, and oral acitretin for severe disease.
Symptoms
- Greasy, crusted, warty brown papules that may coalesce
- Chest, back, neck, forehead and skin folds
- Unpleasant odour, especially in folds
- Alternating red and white nail streaks with V-shaped notching at the tip
- White papules on the palate; pits on palms and soles
Causes & Risk Factors
- Autosomal dominant mutation in the ATP2A2 gene
- Family history in most cases; some new mutations
- Flare triggers: heat, sweating, sunlight, friction, infection, lithium
Treatment & Management
- Cooling measures, loose clothing and sun protection
- Emollients and antiseptic washes to reduce odour and infection
- Topical retinoids and corticosteroids
- Oral acitretin or isotretinoin for widespread disease
- Antibiotics or antivirals for bacterial or herpetic superinfection
When to See a Doctor
See a dermatologist for diagnosis and long-term management. Seek prompt care if lesions become painful, punched-out and rapidly worsen — herpes superinfection is a recognised complication.
Frequently Asked Questions
Is Darier disease inherited by my children?
It is autosomal dominant, so each child of an affected parent has a 50% chance of inheriting the gene, although severity varies widely even within a family.
Why does it smell?
The damaged skin barrier in warm moist folds allows bacterial overgrowth on the crusted papules. Antiseptic washes, cooling and keeping folds dry substantially reduce the odour.
