SPIDER NEVUS Meaning and
Definition
-
Spider nevus, also known as spider angioma or spider telangiectasia, is a common benign vascular skin lesion characterized by a central red spot with small blood vessels radiating outwards resembling spider legs. It is typically found on the face, neck, arms, hands, and upper trunk. Spider nevi are frequently observed in both adults and children, with a higher prevalence in certain populations such as pregnant women, individuals with liver disease, or those who have undergone hormonal changes.
The development of spider nevi is closely linked to the dilation of small blood vessels, or capillaries, which occur due to an abnormality in the blood supply system. This anomaly is often associated with hormonal imbalances or liver dysfunction, specifically an increase in estrogen levels or impaired liver function that impairs the liver's ability to metabolize hormones. As a consequence, the vascular lesions become more apparent. Spider nevi are typically painless and do not cause any symptoms. However, in rare cases, they may be associated with underlying medical conditions that require further investigation.
Treatment of spider nevi is generally not necessary unless there is an underlying liver disease or cosmetic concerns. In such cases, interventions may include laser therapy, electrodessication, or sclerotherapy to minimize or remove the lesions. Preventive measures against spider nevi include managing underlying conditions, maintaining a healthy liver, and avoiding factors that may exacerbate hormonal imbalances. It is recommended to consult a healthcare professional to determine the most appropriate course of action.

Etymology of SPIDER NEVUS
The word "spider nevus" is derived from a combination of two terms: "spider" and "nevus".
1. Spider: The term "spider" in this context refers to its resemblance to a spider's shape. The pattern of arterial dilation within the skin lesion radiates from a central point, branching out like the legs of a spider. The use of the word "spider" is purely descriptive.
2. Nevus: The term "nevus" originates from Latin and means "birthmark". A "nevus" is a general term for any pigmented, non-cancerous growth on the skin, commonly known as a mole.
Thus, when combined, "spider nevus" refers to a specific type of vascular lesion on the skin that resembles the shape of a spider, characterized by arterial dilation resulting in a central red spot with branching blood vessels.
