Nevus Sebaceous: Removal, Cancer, Treatment, and More


Birthmarks are common skin markings that appear at birth or shortly after. They come in various shapes, sizes, and colors and can be found on different parts of the body. Among the many types of birthmarks, scalp birthmarks are particularly intriguing due to their hidden nature. In this article, we will delve into the secrets behind scalp birthmarks, their types, potential causes, and available treatment options.

Definition and Prevalence

Scalp birthmarks, also known as congenital scalp lesions, are marks that appear on the skin of the scalp at birth or within the first few weeks of life. They can vary in size, shape, and color, and may be flat or raised. Scalp birthmarks are relatively common, with studies estimating their prevalence to be around 10% in newborns.

Types of Scalp Birthmarks

a. Vascular Birthmarks:

These birthmarks result from abnormal blood vessels and are further classified into two main types:

i. Salmon Patch (Nevus Simplex): These are flat, pink or red patches commonly found on the back of the neck or forehead. They are caused by dilated blood vessels and usually fade within the first year of life.

ii. Strawberry Hemangioma (Infantile Hemangioma): These birthmarks are characterized by raised, red, and lumpy growths that can appear anywhere on the scalp. They typically grow rapidly in the first few months and then gradually shrink and fade over several years.

b. Pigmented Birthmarks:

Pigmented birthmarks are caused by an overgrowth of pigment cells and can manifest in different forms:

i. Mongolian Spot: These birthmarks are flat, blue-gray patches that commonly appear on the lower back or buttocks. While they are not exclusive to the scalp, they can occur in this area as well.

ii. Café-au-Lait Spot: Café-au-lait spots are light brown patches that can vary in size and shape. They are generally harmless but may indicate an underlying genetic condition when multiple spots are present.

iii. Congenital Melanocytic Nevus: These birthmarks are brown or black in color and can be flat or raised. They can range in size from small to large and may have hair growing from them.

Possible Causes

The exact causes of scalp birthmarks are not always known, but several factors are believed to contribute to their development:

a. Genetic Factors:

In some cases, scalp birthmarks may have a genetic component and can run in families.

b. Embryological Factors:

During embryonic development, abnormalities in the migration or proliferation of cells can result in the formation of birthmarks.

c. Vascular Abnormalities:

Disturbances in blood vessel development can lead to the formation of vascular birthmarks, such as hemangiomas.

d. Hormonal Influences:

Hormonal changes during pregnancy may play a role in the development of certain types of birthmarks.

Treatment Options

Observation and Monitoring

In many cases, scalp birthmarks do not require any treatment and may fade or disappear on their own over time. Regular monitoring by a healthcare professional is essential to ensure their stability and rule out any complications.

Laser Therapy

Laser therapy is a common treatment option for certain types of birthmarks, particularly vascular birthmarks. It works by targeting the abnormal blood vessels, causing them to shrink and fade over time.

Surgical Excision

In some cases, surgical excision may be necessary, especially for large or complex birthmarks that pose a risk to the individual’s health or well-being. Surgical removal is typically performed by a skilled dermatologist or plastic surgeon.


Scalp birthmarks can be a source of curiosity and intrigue, but they are usually harmless. Understanding the different types of birthmarks, their potential causes, and available treatment options can help individuals and parents make informed decisions about their management. If you or your child has a scalp birthmark, it is recommended to consult a healthcare professional who can provide guidance and appropriate care throughout the process. Remember, while birthmarks may be mysterious, they often hold no cause for concern and can be embraced as unique features that make us who we are.
