What does epidermolytic hyperkeratosis look like?
What does epidermolytic hyperkeratosis look like?
Epidermolytic hyperkeratosis (EHK) presents as erythematous, scaly, crusted plaques . (Courtesy J. Conlon, MD.) EHK clinically shows erythematous, scaly plaques, which may present anywhere on the body but predominate around creases and folds (intertriginous areas) .
Can epidermolytic hyperkeratosis be cured?
There is no cure for epidermolytic ichthyosis (EI). The primary goal of therapy is to reduce hyperkeratosis. This can be achieved with topical keratolytics such as lactic acid, alpha-hydroxy acid, or urea. Topical emollients such as those containing glycerin are also often useful.
What is the prognosis of Epidermolytic ichthyosis?
Epidermolytic ichthyosis is a lifelong condition. Some patients may experience amelioration of symptoms as they age. Risk for morbidity and mortality is highest in the neonatal period, where infants are at increased risk for complications such as sepsis and dehydration because of impaired barrier function.
Is epidermolytic hyperkeratosis a rare disease?
Epidermolytic ichthyosis (EI) is a rare, genetic skin disorder. It becomes apparent at birth, or shortly after birth, with reddening, scaling, and severe blistering of the skin. Hyperkeratosis (thickening of the skin) develops within months and worsens over time.
How common is epidermolytic hyperkeratosis?
Epidermolytic hyperkeratosis affects approximately 1 in 200,000 to 300,000 people worldwide.
What are the symptoms of Epidermolytic ichthyosis?
What are the clinical features of epidermolytic ichthyosis?
- Widespread erythroderma, blisters, and superficial ulceration at birth.
- Peeling, erosions, and denuded skin after minor friction or trauma.
- Improvement with age; blistering is replaced by dark-brown, grey, or white dry or macerated scales and erythema.
How does Epidermolytic hyperkeratosis affect the skin?
As affected individuals get older, blistering is less frequent, erythroderma becomes less evident, and the skin becomes thick (hyperkeratotic ), especially over joints, on areas of skin that come into contact with each other, or on the scalp or neck. This thickened skin is usually darker than normal.
What is Sjogren Larsson Syndrome?
Sjögren-Larsson syndrome (SLS) is an inherited disorder characterized by scaling skin (ichthyosis), intellectual disability, speech abnormalities, and spasticity. Affected infants develop various degrees of reddened skin with fine scales soon after birth.
What kind of skin does epidermolytic hyperkeratosis have?
People with PS-type epidermolytic hyperkeratosis have thick skin on the palms of their hands and soles of their feet (palmoplantar or palm/sole hyperkeratosis) in addition to other areas of the body.
What causes hyperkeratosis of the palms and soles?
It is possible to classify epidermolytic hyperkeratosis based upon palm and sole hyperkeratosis. This is a dominant genetic condition caused by mutations in the genes encoding the proteins keratin 1 or keratin 10. Keratin 1 is associated with the variants affecting the palms and soles.
What kind of genes are involved in hyperkeratosis?
Mutations in the KRT1 or KRT10 genes are responsible for epidermolytic hyperkeratosis. These genes provide instructions for making proteins called keratin 1 and keratin 10, which are found in cells called keratinocytes in the outer layer of the skin (the epidermis).
Is there a cure for hyperkeratosis without gene therapy?
The condition is caused by a genetic mutation, so it cannot be completely cured without some form of gene therapy. While some research has been done into possible gene therapy treatments, the work hasn’t yet been successfully developed to the stage where it can be routinely given to patients.
