Symptoms
A spider nevus is usually 0.2 to 1.0 centimeters in size, but can also be several centimeters in size. It is a vascular dilatation with a small, red, dot-like, raised vascular node in the middle. From this vascular nodule, small vessels run outwards like a spider’s web or star-shaped. Spider naevi are found on light-exposed skin and are therefore often found on the head, forehead and neck. There are also Spider Naevi in the trunk area and on the hands.
Therapy
A Spider naevus does not normally require treatment. The cause of the change should be examined and treated if necessary. If the spider nevus is disturbing for cosmetic reasons, the spider nevus can be removed with a laser or a diathermy needle.
Spider nevi can be removed with a medical laser. Deep lasers are used to treat the dilated vessels by means of heat coagulation. Several laser sessions may be necessary for the spider naevi to disappear completely. Since spider naevi are arterial vascular dilatations of the skin, there are no home remedies that can eliminate these changes.
Duration
Spider naevi are small changes on the skin surface caused by vascular changes. The number and development over time of the development of the nevi depends on the underlying cause of the nevi, as does the prognosis. If severe liver disease is the underlying cause of the symptoms, the stage and treatment of the liver disease will determine the prognosis.
Course of disease
Especially if there are many and dense Spider naevi, a disease must be excluded. A cosmetic removal can remove the benign vascular changes. If spider naevi are caused by hormones, for example during pregnancy, the changes often regress after delivery.
