Iron supplementation should be avoided as iron can increase photosensitivity in EPP.
Afamelanotide has been reported to be effective for EPP.
It is approved for the treatment of EPP under orphan drug status.

People with EPP who also have liver disease require specialist medical treatment and possibly a liver transplant.
The condition affects one in every 500,000 babies born every year in the United States.
The likelihood of having a rare skin disorder is 25% if both parents pass down the gene.

If only one parent has the gene, its unlikely that the condition will develop.
Antibiotic treatment is needed to prevent or treat infections at this time.

The main symptom of elastoderma is loose skin that sags or hangs in folds.
The skin is not stretchy and can often appear wrinkled.
Other symptoms include:
Most people with the skin condition will have one or more symptoms.
Eczema and bacterial infections on the upper layer of the skin have also been found in those with elastoderma.
The cause of elastoderma is largely unknown.
It is not clear what causes this increase in elastin in people with this condition.
There is no known cure for elastoderma.
The exact cause of IGD is unknown, but this condition has been associated with otherautoimmune diseases.
Research has suggested that it is a cutaneous form of rheumatoid arthritis.
Treatment options for the disease are typically topical steroids or hydroxychloroquine.
The throw in of pemphigus depends on where the blisters form, and some are fatal if left untreated.
Older adults tend to have this condition, but it can affect people at any age.
The prevalence increases with age, and both men and women were affected equally.
The main symptom of pemphigus is blisters on the skin that rupture and become open sores.
Blisters can appear suddenly and spread, and can linger for years.
Sores heal slowly, and when they heal, they turn into a dark spot.
Pemphigus foliaceus affects only the skin and often develops on the face, scalp, and upper body.
There is also drug-induced pemphigus, which is.
a result of taking certain medications.

They will be cleaned and protected from further contamination.
Antibiotic medications will also be applied to the wounds to prevent infections.

Soft diets may help until the lesions heal.
Some foods may trigger the onset of more sores, including garlic, onions, and leeks.
Occasionally, peeling may also occur on the arms and legs.
The peeling is made worse by heat, humidity, and other forms of moisture and friction.
Other symptoms may include:
The affected areas typically heal without scarring.

Typically, the best time to apply creams is when the skin is moist following a bath.
If blister develop, they may be lanced with a sterile needle.
Light dressings should be applied to prevent infection.
Harlequin ichthyosis is because of mutations affecting the ABCA12 gene.
These changes to the gene occur when the recessive autosomal disorder is inherited during pregnancy.
It is possible for people to live to adulthood with harlequin ichthyosis.
