Seborrheic Keratosis

Understanding Seborrheic Keratosis: Identification and Treatment

Seborrheic Keratosis, also known as seborrheic verruca, is a common and generally benign skin growth that often appears as brown, black, or yellow lesions. These growths may occur singly or in clusters and can be flat or slightly raised, often resembling warts. While typically harmless, they can vary in color, size, and texture, leading many individuals to seek professional evaluation and possible removal. Most people will develop at least one seborrheic keratosis at some point in their lives.

Although seborrheic keratosis does not pose a cancer risk, recognizing its distinctive appearance is essential. Due to their resemblance to precancerous growths like actinic keratosis, your dermatologist may perform a biopsy to confirm the diagnosis. Monitoring any changes and consulting with a professional dermatologist ensures accurate identification and alleviates concerns about these typically benign but sometimes cosmetically bothersome skin growths.

By minimizing risk factors related to seborrheic keratosis, you may be able to prevent the development of these benign skin growths. While some factors are beyond control, implementing certain lifestyle measures can contribute to overall skin health:

Sun Protection: Given the potential link between sun exposure and seborrheic keratosis, protecting the skin from harmful UV rays is crucial. Regular use of sunscreen with adequate sun protection factor (SPF) and wearing protective clothing can mitigate the impact of ultraviolet radiation.

Hygiene and Skincare: Maintaining good skincare practices can be beneficial such as gentle cleansing routines, moisturizing, and regular dermatologist visits.

Genetic Awareness: Since there is a familial predisposition to seborrheic keratosis, individuals with a family history should remain vigilant. Regular skin checks and early consultation with one of our dermatologists can aid in timely detection and management.

Healthy Lifestyle: Embracing a healthy lifestyle with a balanced diet, regular exercise, and avoiding tobacco can promote overall well-being, potentially influencing skin health.

While these measures may support skin health, seborrheic keratosis remains challenging to prevent entirely, as genetic factors and aging are significant contributors. Regular at-home skin checks, annual Total Body Skin Exams, and bringing attention to any suspicious growths are crucial for early detection and treatment. 

Generally, no treatment is required unless the growth becomes irritated from chafing against clothing. However, because it looks similar in appearance to precancerous growths (actinic keratosis), your dermatologist will likely biopsy the tissue to confirm the diagnosis.
If a seborrheic keratosis becomes irritated or unsightly, removal is conducted using one of these three methods:

• Cryosurgery: freezes off the growth using liquid nitrogen.
• Curettage: the dermatologist scrapes the growth off the surface of the skin.
• Electrocautery: used alone or in conjunction with curettage to burn off the tissue and stop the bleeding.
