What is seborrheic keratosis?

Seborrheic keratosis is a skin growth that can resemble a wart or mole. They typically affect middle-aged and older people, but they can occur earlier. Many people who develop seborrheic keratosis have several lesions.

While harmless, seborrheic keratosis can be cosmetically bothersome or cause discomfort if they rub against clothing. An accurate diagnosis is essential to distinguish these benign growths from more serious conditions, like skin cancer.

What does seborrheic keratosis look and feel like?

Seborrheic keratosis typically has the following characteristics:

Color

They can vary in color, appearing tan, brown, black, or even have a waxy, scaly appearance.

Texture

The texture of seborrheic keratosis is often rough or wart-like, and it may have a stuck-on or pasted-on appearance on the skin.

Shape

Seborrheic keratosis lesions can be round or oval and may have well-defined borders. They generally appear elevated from the skin surface.

Size

They vary in size, ranging from very small to larger than a centimeter in diameter.

Quantity

Multiple seborrheic keratoses may develop, and they can appear on various areas of the body, commonly on the face, chest, shoulders, or back.

Itching

While seborrheic keratoses are typically asymptomatic, some individuals may experience itching, especially if clothing or jewelry rubs against them.

What causes seborrheic keratosis?

Seborrheic keratosis occurs when skin cells called keratinocytes grow and multiply rapidly. Factors that can increase your risk of lesions developing include:

• A family history of seborrheic keratosis
• Repeated sun exposure
• Hormonal fluctuations, especially during pregnancy
• Vital infections, including the human papillomavirus (HPV)
• Older age

In some cases, multiple seborrheic keratoses appearing suddenly can signal an underlying medical condition. A prompt diagnosis is crucial to rule out any potential serious health issues.

What are the most effective treatments for seborrheic keratosis?

While seborrheic keratoses don’t usually need to be removed, you may choose to treat them for cosmetic purposes.
