Seborrheic Keratosis | SK
Seborrheic keratosis is a common, non-cancerous skin growth that typically appears in older adults. These growths often look like waxy, brown, or black bumps, and while they can develop anywhere on the body, they are most commonly found on the chest, back, shoulders, or face. Despite their sometimes alarming appearance, seborrheic keratoses are harmless and do not turn into skin cancer.
What Causes Seborrheic Keratosis?
The exact cause of seborrheic keratosis isn’t fully understood, but they tend to run in families, suggesting a genetic link. Sun exposure may play a role in their development, though they can also occur on areas not commonly exposed to sunlight.
Symptoms and Appearance
Color: Ranges from light tan to dark brown or black.
Texture: Often described as waxy, wart-like, or scaly. Some may appear flat, while others are slightly raised.
Size: Growths can vary in size from small (less than 1 cm) to larger patches (over 2.5 cm).
Shape: Usually round or oval.
Seborrheic keratoses may itch or become irritated, especially if they catch on clothing. Although they’re benign, many patients choose to have them removed for cosmetic reasons or to ease discomfort.
Diagnosis and Treatment Options
Our dermatologists can typically diagnose seborrheic keratosis by examining the growth. In some cases, a biopsy may be performed to confirm that it’s not a more serious condition, such as melanoma.
While seborrheic keratoses don’t require treatment, options for removal include:
Cryotherapy: Freezing the growth with liquid nitrogen.
Curettage: Scraping off the growth.
Electrosurgery: Burning the growth off using electric currents.
When to See a Doctor
Seborrheic keratosis is benign, but it’s important to consult our dermatologists if:
You notice rapid changes in the growth’s appearance.
It starts to bleed, becomes painful, or becomes easily irritated.
You’re uncertain whether a new skin lesion is seborrheic keratosis or something else, such as melanoma.
Prevention
Since the cause is largely genetic, there is no sure way to prevent seborrheic keratosis. However, regular skin checks and protecting your skin from excessive sun exposure can help maintain overall skin health.
