What is Seborrheic Keratosis?
Seborrheic Keratosis (SK) is a common, benign (noncancerous) skin growth. These growths often appear in middle age or later and can resemble warts, moles, or skin cancer, but they are harmless.
Symptoms of Seborrheic Keratosis
- Appearance: SKs are usually round or oval, with a “stuck-on” look. They can be brown, black, tan, or sometimes pink, yellow, or white.
- Texture: They may feel waxy, scaly, or rough, and can be flat or slightly raised.
- Size: They can range from very small to over an inch in diameter.
- Location: SKs can appear anywhere on the body except the palms and soles, commonly on the face, chest, shoulders, back, and scalp.
Risk Factors
- Age: More common in people over 50.
- Family History: A tendency to develop SKs can be inherited.
- Sun Exposure: While not directly caused by sun exposure, UV radiation can contribute to their development.
- Skin Type: More frequent in people with lighter skin tones.
Prevention Tips
- Sun Protection: Use sunscreen and wear protective clothing to minimize UV exposure.
- Regular Skin Checks: Monitor your skin for any new or changing growths and consult a dermatologist if you notice anything unusual.
Diagnosis
A dermatologist can usually diagnose SK by examining the skin. If there’s any doubt, a biopsy may be performed to rule out other conditions.
Treatment Options
- Cryotherapy: Freezing the growth with liquid nitrogen.
- Curettage: Scraping off the growth, sometimes followed by electrosurgery.
- Laser Therapy: Using laser light to remove the growth.
- Topical Treatments: Applying creams or gels to help remove the growth.
