Vascular spider

Vascular spider (also known as spider angioma, spider nevus, or telangiectasia) is a common benign vascular anomaly that may appear as a solitary lesion or as multiple lesions. It is characterized by a central red spot surrounded by radiating vessels, resembling a spider's web.

Causes

The exact cause of vascular spiders is unknown, but they are associated with high levels of estrogen. They are commonly seen in pregnancy and in individuals with liver disease, especially cirrhosis. They can also occur in healthy individuals without any underlying medical conditions.

Symptoms

Vascular spiders are usually asymptomatic, but they can cause cosmetic concerns due to their appearance. They are typically red or purple in color and can vary in size from a few millimeters to several centimeters. They are most commonly found on the face, neck, upper chest, and arms.

Diagnosis

The diagnosis of a vascular spider is usually made based on the characteristic appearance of the lesion. In some cases, a dermatoscope may be used to visualize the lesion more clearly. If the diagnosis is uncertain, a skin biopsy may be performed.

Treatment

Treatment is not usually necessary for vascular spiders unless they are causing cosmetic concerns or discomfort. If treatment is desired, options include laser therapy, sclerotherapy, and electrocautery. These treatments work by destroying the blood vessels in the lesion, causing it to fade or disappear.
