Seborrheic Keratosis

Seborrheic Keratosis, also known as seborrheic verruca, is a common and typically benign skin growth, often appearing as brown, black or yellow growths that grow singly or in groups and are flat or slightly elevated. Often they are mistaken for warts. While these growths are generally harmless, they can vary in color, size, and texture, causing individuals to seek professional care for diagnosis and removal. Most people will develop at least one seborrheic keratosis during a lifetime. 

Although they do not pose a cancer risk, understanding their distinctive  appearance is important. Because they look similar in appearance to precancerous growths (actinic keratosis), your dermatology professional at Pittsburgh Dermatology and Skin Cancer Center will likely biopsy the tissue to confirm the diagnosis. Monitoring for changes and seeking dermatologic care from one of our professionals ensures accurate identification and alleviates concerns related to these generally harmless, yet sometimes aesthetically 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.
