Relapsing Linear Acantholytic Dermatosis is a skin disorder characterized by recurring red patches or lines on the skin due to the separation of skin cells.
Types
There’s primarily one type of RLAD, but it can vary in severity and appearance from person to person.
RLAD primarily comes in two main types:
- Darier’s Disease (DD): This type of RLAD is characterized by the formation of small, bumpy, and crusty papules on the skin, often seen on the chest and back.
- Hailey-Hailey Disease (HHD): HHD is similar to DD but usually affects the neck, armpits, and groin area, resulting in painful red plaques.
Causes
- Genetics: Inherited genes may increase susceptibility.
- Hormones: Changes can influence skin conditions.
- Immune System: Abnormal reactions may cause skin cell separation.
- Infections: Some viruses or bacteria might trigger it.
- Drugs: Reactions to certain medications.
- Stress: Emotional stress can be a factor.
- UV Radiation: Excessive sun exposure.
- Trauma: Physical injury to the skin.
- Friction: Consistent rubbing can lead to symptoms.
- Heat: Excessive heat can influence outbreaks.
- Allergens: Reaction to specific substances.
- Chemicals: Harsh substances irritating the skin.
- Diet: Some foods might trigger symptoms.
- Autoimmune Reaction: Body attacking its own skin cells.
- Age: More common in certain age groups.
- Underlying Diseases: Like kidney or liver conditions.
