Spitz nevus: symptoms, images, AI check ⚠️ ICD-10: D22 | ICD-11: 2F20

Spitz nevus is a benign skin lesion, most often appearing as a small raised nodule on the skin. It usually develops in childhood or adolescence and is not contagious.

It is most often a solitary lesion with well-defined borders and uniform coloration, ranging from pink to brown. In most cases, Spitz nevus is harmless and does not progress to skin cancer.

Sometimes it may grow slightly over time, but usually remains stable and does not cause discomfort.

What to Do if You Suspect a Spitz Nevus

If you notice a new lesion resembling a Spitz nevus, it is important not to panic—this is a common and usually safe condition.

First step: consult a dermatologist. If necessary, the doctor may refer you to an oncologist for further evaluation.

The doctor will perform a skin examination and dermoscopy—a painless method in which the lesion is examined under magnification. In some cases, a biopsy (removal of a small tissue sample for analysis) may be needed to rule out malignancy.

Important: Do not attempt to treat or remove the lesion yourself. Do not ignore changes—timely consultation helps reduce risks and choose the appropriate monitoring or treatment strategy.

Appearance

Spitz nevus usually appears as a small dome-shaped or slightly flattened nodule on the skin. It is often symmetrical, with smooth and well-defined borders.

Color may vary: from light pink or flesh-colored to brown. The pigmentation is usually uniform, sometimes with subtle shading. The surface may be smooth or slightly bumpy.

Size: usually 3–8 mm in diameter, with height of a few millimeters above the skin. Hair usually does not grow on the lesion—a characteristic feature.

Common locations:

• Face
• Neck
• Limbs
• Less commonly, the trunk

Over time, the nevus may change slightly, but in most cases it maintains its symmetrical shape and clear borders.

Main Symptoms

In most cases, Spitz nevus does not cause any discomfort.

Key features:

• Small raised lesion on the skin
• Symmetrical shape with clear borders
• Uniform color
• No pain, itching, or burning

When pressed, it may feel slightly firmer than surrounding skin.

Causes

The exact cause of Spitz nevus is unknown, but several factors may play a role.

External factors:

• Ultraviolet (UV) exposure (sunlight or tanning beds)

Internal factors:

• Genetic predisposition
• Hormonal changes (e.g., during adolescence or pregnancy)

These factors do not always lead to the formation of a nevus, but may increase the likelihood.

How Spitz Nevus Develops

Spitz nevus forms from melanocytes—the skin cells responsible for pigment production.

Under various influences, these cells start dividing actively, forming a small nodule. The process remains benign—cells do not invade surrounding tissue and do not behave like cancer.

Forms and Types

There are several variants of Spitz nevus, based on cell structure and appearance.

For patients, this distinction is usually not significant, as monitoring or treatment strategies are determined individually by the doctor.

When to See a Doctor

Consult a doctor if:

• The lesion appeared recently and is growing quickly
• Color, shape, or size has changed
• Pain, itching, or burning occurs
• The nevus has been traumatized
• The lesion is repeatedly rubbed by clothing or jewelry

Even without these signs, periodic dermatological checks are recommended, especially if multiple lesions are present.

Treatment

In most cases, Spitz nevus does not require urgent treatment and can be monitored.

Approaches include:

• Regular check-ups (including photographic monitoring if necessary)
• Gentle skin care
• Avoiding trauma to the lesion

If there is diagnostic uncertainty, risk of damage, or changes in appearance, a doctor may recommend surgical removal.

Surgical removal is usually followed by histological examination to confirm the diagnosis.

Tissue-destructive methods (e.g., laser or cryotherapy) are generally not used, as preserving tissue for analysis is important.

Treatment method is always determined individually by the doctor.

Q&A

Is Spitz nevus dangerous?

In most cases, it is a benign, safe lesion that does not increase the risk of melanoma.

Can Spitz nevus be “treated”?

It is not “treated” in the conventional sense, but can be fully removed surgically if needed.

Does Spitz nevus need removal?

Not always—the decision is made by a doctor if changes occur, trauma risk exists, or diagnosis is uncertain.

Can Spitz nevus disappear on its own?

Sometimes it may slightly shrink, but usually remains stable.

Can you sunbathe with Spitz nevus?

Sun exposure should be limited, and sunscreen used to reduce the risk of changes.

How is Spitz nevus different from melanoma?

Spitz nevus is usually symmetrical with uniform color, whereas melanoma often has irregular borders and uneven pigmentation. Only a doctor can provide an accurate diagnosis.

Should a stable Spitz nevus be monitored?

Yes, periodic checks are recommended to detect changes early.

Can Spitz nevus be traumatized?

Accidental trauma can occur, but repeated irritation should be avoided to prevent changes and the need for removal.
