Introduction
In patients with liver disease, cirrhosis may lead to significant loss of liver function, causing excessive dilation of small skin arteries and resulting in spider angiomas. There are various causes of spider angiomas; apart from liver disease, individuals with endocrine disorders or pregnant women who have elevated estrogen levels are also prone to developing spider angiomas.
Spider angioma is a skin abnormality characterized by the expansion of capillaries in the skin, distributed in a radiating pattern resembling a spider. It may be associated with liver cirrhosis, but not necessarily.
1. Possible association
In patients with acute or chronic hepatitis, alcoholic hepatitis, or viral hepatitis, if the disease course is prolonged and treatment ineffective, significant liver cell damage may occur. This can lead to fibrosis of liver tissue and eventually cirrhosis, resulting in substantial loss of liver function. As a consequence, the liver's ability to inactivate estrogen may be reduced or lost, causing excessive dilation of small cutaneous arteries and forming spider angiomas.
2. May not be related
There are various causes of spider angiomas. Besides liver diseases, individuals with endocrine disorders or pregnant women who have elevated estrogen levels in the body are also prone to developing spider angiomas.
When spider angiomas are small in size and area, physical treatments such as carbon dioxide laser therapy or high-frequency electrocautery can be used to destroy the central blood vessel and improve symptoms. If these treatments are ineffective, surgical excision may be considered to alleviate the condition.
