Causes
This condition is caused by mutations in specific genes that play a role in the formation of the skin barrier. Lamellar ichthyosis is a rare genetic skin disorder characterized by abnormal skin shedding. The overproduction of skin cells results in thick scales that cover the body as a result of these mutations.
Symptoms
Lamellar ichthyosis typically presents with the following symptoms at birth or shortly thereafter:
-
It has thick, plate-like scales covering most or all of its body, resembling fish scales.
-
A condition in which the eyelids turn outward, causing irritation or dryness of the eyes.
-
The lips are everted, resulting in difficulty closing the mouth fully.
-
Inability to regulate body temperature due to impaired sweating.
-
Scale buildup restricts movement of joints.
Diagnosis
A combination of clinical evaluation, family history assessment, and genetic testing is required to diagnose lamellar ichthyosis:
-
Examining the skin to assess the presence and distribution of scales, as well as any associated features such as ectropion or eclabium.
-
Inquiring about a family history of similar skin conditions, since lamellar ichthyosis is an autosomal recessive disease.
-
Testing for mutations in genes associated with lamellar ichthyosis, such as the TGM1 gene and the ALOX12B gene.
Treatment
There is no cure for lamellar ichthyosis, but treatment aims to manage symptoms and improve skin hydration:
-
A regular application of emollients and moisturizers softens and hydrates the skin, reducing the severity of scaling and preventing fissures.
-
A prescription cream or ointment containing keratolytic agents, such as urea or salicylic acid, can remove scales and improve skin texture.
-
Soaking in warm baths and gently exfoliating the skin with a soft washcloth can help remove excess scales. Adding oil or oatmeal to the bathwater can also soothe the skin.
-
To prevent dryness and irritation associated with ectropion, use eye drops or ointments that lubricate the eyes.
-
In order to prevent joint contractures and maintain mobility, stretching exercises and physical therapy may be recommended.
Prevention
Lamellar ichthyosis is a genetic disorder, so prevention involves genetic counseling and testing, especially for people with a family history of the condition. Prenatal testing is also available for couples at risk.
Conclusion
The skin condition lamellar ichthyosis is characterized by thick, plate-like scales covering the body. Diagnosis involves clinical evaluation and genetic testing, and treatment includes managing symptoms and hydrating the skin. It is not possible to cure lamellar ichthyosis, but early intervention and appropriate skincare can help to improve symptoms.
