What is erythema Dyschromicum Perstans?

Erythema dyschromicum perstans (EDP), also called ashy dermatosis, is a rare acquired and chronic dermatosis, characterized by asymptomatically and progressively hyperpigmented macules of various size on the trunk, face, and extremities.

How do you treat Perstans erythema Dyschromicum?

Treatments that may help improve the appearance of erythema dyschromicum perstans include:

1. Topical steroids.
2. Exposure to ultraviolet radiation.
3. Pigment lasers, such as Q-switched ruby laser.
4. Chemical peels.

What is EDP syndrome?

Erythema dyschromicum perstans (EDP), also known as ashy dermatosis and dermatosis cenicienta, is a benign, uncommon skin condition that presents with generalized ashy-gray colored macules on the body. Many consider this condition to be a variant of lichen planus.

How long does ashy dermatosis last?

Punch biopsy may be indicated to exclude other causes of hyperpigmentation, particularly lichen planus. The clinical course of ashy dermatosis is different between children and adults. In children, ashy dermatosis typically resolves in two to three years [2, 40].

Can lichen planus Pigmentosus cured?

There are currently no effective treatments for lichen planus pigmentosus (LPP) and erythema dyschromicum perstans (EDP). Tranexamic acid, which may downregulate pigmentation through a reduction in plasmin, has been shown to decrease pigmentation in patients with melasma, another pigmentary disorder.

Is there a cure for ashy dermatosis?

No gold standard treatments have been established yet. The most successful treatment to date has been clofazimine, although topical tacrolimus, oral dapsone, narrowband ultraviolet light B phototherapy, and isotretinoin have shown treatment success.

Is erythema Dyschromicum Perstans curable?

Because EDP is an uncommon disease of the skin, it is important to consider other skin diseases that may resemble erythema dyschromicum perstans, such as infectious diseases (i.e. leprosy or pinta), reaction to drugs, post inflammatory hyperpigmentation, or lichen planus pigmentosus. There is no cure for EDP.

How do you get rid of lichen planus Pigmentosus?

Treatment

1. Vitamin A.
2. Topical corticosteroids.
3. Topical calcineurin inhibitors such as tacrolimus (medications that are typically used to treat eczema)
4. Dapsone (a medication used to treat leprosy and skin infections)
5. Skin lightening agents.
6. Laser therapy.

What is the best treatment for lichen planopilaris?

Light therapy (phototherapy) may help clear up lichen planus affecting the skin. The most common phototherapy for lichen planus uses ultraviolet B (UVB) light, which penetrates only the upper layer of skin (epidermis). Light therapy usually requires two to three treatments a week for several weeks.

What causes ashy dermatosis?

The cause of ashy dermatosis is still unknown. It’s suspected to be caused by exposure to ammonium nitrate, a chemical that is found in fertilizer. Whipworms, a type of intestinal parasite, have also been suggested as a possible cause.

What is erythema infectious?

Erythema infectiosum is caused by an erythrovirus, EVB19 or Parvovirus B19. It is a single-stranded DNA virus that targets red cells in the bone marrow. It spreads via respiratory droplets, and has an incubation period of 7–10 days.
