Keratosis Linearis with Ichthyosis Congenita (KLIC) is a rare skin disorder. It involves the abnormal growth of keratin on the skin, combined with a skin condition present from birth known as ichthyosis congenita. Keratin is a protein that forms the main structural component of hair and nails. Ichthyosis congenita makes the skin appear scaly, similar to fish scales.
Keratosis Linearis with Ichthyosis Congenita (KLICK) is a rare skin condition that affects people from a young age. This article will provide a simplified, easily understandable overview of KLICK. We will discuss the types, causes, symptoms, diagnostic tests, treatments, and medications associated with this condition.

- Non-Syndromic KLICK: This type of KLICK occurs on its own without any other health issues.
- Syndromic KLICK: In syndromic KLICK, the skin condition is associated with other health problems, making it more complex to manage.
Causes:
While the exact causes are not always clear, some potential triggers or related factors include:

- Pain: Some areas can be painful.
- Cracking: Skin might develop cracks.
- Blistering: Blisters might form.
- Inflammation: Swelling and warmth in affected areas.
- Thickened Skin: Over time, skin might become thicker.
Diagnostic Tests:
To diagnose KLIC, the following might be performed:
- Physical Examination: A simple visual check of the skin.
- Biopsy: Taking a small sample of skin for testing.
- Blood Tests: To check for underlying causes.
- Genetic Testing: To see if it’s hereditary.
- Allergy Tests: Identify potential allergens.
- Hormone Tests: Check hormonal levels.
- Microscopy: Examining skin cells under a microscope.
- Imaging Tests: Like X-rays or MRIs to see skin layers.
- Patch Tests: Applying substances to the skin to check for reactions.
- Skin Scraping: To check for infections or other conditions.
