What is a vascular nevus?

A vascular nevus is a benign tumor made up of blood vessels and capillaries that form a small nodule or spot on the skin. It can be red, purple or blue in color and is usually flat or convex in appearance.

Signs of vascular nevus

A vascular nevus usually looks like a bright red or purple spot on the skin. It may be flat or convex and have an uneven surface. It can range in size from small spots to larger nodules.

Causes of vascular nevus

The causes of vascular nevi can vary. They can occur due to genetic predisposition, exposure to ultraviolet rays, changes in the hormonal background or other factors.

Types of vascular nevi

Vascular nevi can have different shapes and structures. Some may be capillary, while others may be cavernous or combined. It is important to distinguish between them to determine treatment and removal methods.

Let's break down the main types of vascular nevi in more detail:

  1. Capillary nevus: This type of nevus is formed from capillaries, small blood vessels that are usually closer to the surface of the skin. Capillary nevi are usually bright red or purple in color and can be flat or convex.
  2. Cavernous nevus: This type of nevus consists of cavernous vessels, which are larger in size and can form deep nodules in the skin. Cavernous nevi are usually dark blue or purple in color and may be more bulging and soft to the touch.
  3. Combined nevus: This type of nevus includes elements of both capillary and cavernous vessels. They can have different shapes and colors depending on the combination of capillary and cavernous elements.
  4. Linear nevus of Gunn: This type of nevus is usually a linear arrangement of spots or streaks on the skin. It can be capillary or cavernous and is most commonly found in children.
  5. Nevus Flammeus: This type of nevus is also known as a "port-wine spot" and is usually red or pink in color. It is most often localized on the face and can be associated with vascular abnormalities.

These are the main types of vascular nevi, but they can have different variations depending on their size, shape, color, and location on the body. It is important to see a dermatologist for an accurate diagnosis and to determine the best approach to treatment and removal.

Treatment and removal of vascular nevi

Treatment of vascular nevi depends on their size, location, and other factors. Small and safe nevi usually do not require treatment, but they may be removed for cosmetic purposes or if there is discomfort. Removal of the nevus can be accomplished through a variety of methods including surgical removal, cryodestruction, electrocoagulation, or laser removal.

Vascular nevus, according to the International Statistical Classification of Diseases and Related Health Problems, 10th Revision (ICD-10), has its own code for classification and diagnosis.


In conclusion, vascular nevi, although often presenting as safe changes on the skin, require attention and sometimes medical intervention. The variety of their types, including capillary, cavernous, combined, and others, allows dermatologists to individualize each case for effective treatment.

It is important to know that vascular nevi can occur for a variety of reasons, including genetic predisposition, exposure to ultraviolet radiation, hormonal changes, and other factors. This diverse range of causes also requires an appropriate approach to nevus treatment and removal.

Treatment of vascular nevi can include a variety of methods such as laser removal, surgery, cryodestruction, and other procedures. Determining the best method depends on many factors, including size, location, and desired results.

While most vascular nevi are safe, it is important to seek consultation with a qualified professional for accurate diagnosis and treatment. Seeking treatment early can help prevent potential complications and ensure optimal treatment outcomes.
