Which skin condition is often associated with advanced liver disease?

Spider naevi, also known as spider angiomas, are small, dilated blood vessels that are often seen on the skin and are commonly associated with advanced liver disease. This condition occurs due to the liver's impaired ability to metabolize estrogen, leading to the proliferation of small blood vessels. Individuals with liver dysfunction may develop these vascular lesions, which are typically harmless but serve as a dermatological sign of potential underlying liver issues.

Other conditions listed, such as psoriasis, eczema, and alopecia, are not specifically linked to liver disease in the same way. While they can occur in various contexts, they do not have the direct association with liver pathology that spider naevi do. This specificity makes spider naevi a key indicator in the assessment of liver health and conditions.
