Seborrheic keratoses are non-cancerous growths that develop from the outer layer of the skin. They commonly appear with age and may increase in number over time.

These growths often have a characteristic appearance described as:

• Waxy or “stuck-on”
• Slightly raised or thickened
• Tan, brown, or darker in color
• Smooth or rough in texture

They can occur anywhere on the body except the palms and soles and are most frequently seen on the face, chest, back, and scalp.

The exact cause of seborrheic keratoses is not fully understood, but they are strongly associated with aging and genetic predisposition.

Factors that may contribute include:

• Family history
• Natural aging of the skin
• Long-term environmental exposure

Unlike some other skin lesions, seborrheic keratoses are not caused by sun exposure alone and are not contagious.

Seborrheic keratoses can vary in size, color, and number.

They may appear as:

• Single or multiple growths
• Flat or raised lesions
• Light tan to dark brown or black spots

Some may become thicker or more textured over time.

In certain cases, they may become:

• Itchy
• Irritated by clothing or friction
• Inflamed or crusted

Changes such as these often prompt evaluation.

Clinical Examination

Diagnosis is typically made through a careful visual examination.

Key features—such as texture, color, and border—help distinguish seborrheic keratoses from other lesions.

Dermoscopy

Dermoscopy may be used to examine the lesion more closely and confirm its benign nature.

This technique improves diagnostic accuracy and helps differentiate seborrheic keratoses from moles or other pigmented lesions.

Biopsy When Needed

If a lesion appears atypical or unclear, a biopsy may be performed.

This involves removing a portion or all of the lesion for microscopic evaluation to ensure accurate diagnosis.

Observation

Because seborrheic keratoses are benign, treatment is not medically necessary in most cases.

Many patients choose to leave them untreated once reassured of their benign nature.

Removal for Symptomatic or Cosmetic Reasons

Treatment may be recommended when lesions are:

• Irritated or inflamed
• Frequently caught on clothing or jewelry
• Cosmetically bothersome

Common treatment options include:

• Cryotherapy (freezing the lesion)
• Electrocautery
• Gentle curettage (removal of the growth)

The method selected depends on the size, thickness, and location of the lesion.

Cosmetic Considerations

When removal is performed, attention is given to achieving a smooth, natural appearance of the skin.

Healing is typically straightforward, although temporary discoloration or mild irritation may occur as the skin recovers.

Treatment is performed in the office and is generally quick and well tolerated.

Most procedures take only a few minutes, depending on the number of lesions being treated.

After treatment, patients are given simple aftercare instructions to support healing.

Recovery is usually minimal.

Patients may experience:

• Mild redness or irritation
• Formation of a small scab in treated areas
• Gradual healing over several days to weeks

Most patients are able to resume normal activities immediately.

Even though seborrheic keratoses are benign, evaluation is recommended if a lesion:

• Changes in appearance
• Becomes symptomatic
• Looks different from other growths
• Raises any concern

Accurate diagnosis is important to distinguish these growths from other skin conditions.
