What is Seborrheic Keratosis?
Seborrheic keratosis is a non-cancerous skin growth that develops from the outer layer of skin cells. These lesions can vary in color, ranging from light tan to black, and they often have a waxy or scaly texture. While some individuals develop only one or two growths, others may develop clusters of seborrheic keratoses. They typically appear on areas of the body that are exposed to the sun, such as the face, neck, chest, and back.
Causes
The exact cause of seborrheic keratosis is not fully understood, but it is believed to be related to genetic factors. They are more likely to develop in individuals over the age of 50 and often run in families. Unlike other skin growths, seborrheic keratoses are not caused by sun exposure, and they do not pose any increased risk of skin cancer. However, their appearance can sometimes resemble more serious conditions, making proper diagnosis important.
Symptoms
The primary symptoms of seborrheic keratosis include:
- Waxy, scaly appearance. These growths often look like they’ve been “stuck” onto the skin’s surface.
- Varied colors. They can range from tan, brown, or black, often appearing darker over time.
- Irregular shape. Seborrheic keratoses can be round or oval and may have a rough texture.
- Itchiness. In some cases, these growths may itch or become irritated when rubbed against clothing.
What Are the Possible Treatments?
While seborrheic keratosis does not require treatment, many people opt to have the growths removed for cosmetic reasons or due to discomfort. At Metropolis Dermatology, we offer several advanced treatments, including:
- Laser Treatment: Targeting the growth with lasers to remove it with minimal scarring.
Other recommended treatments:
- Cryotherapy. Freezing the growth with liquid nitrogen to remove it.
- Curettage. Scraping off the growth with a sharp tool after numbing the area.
- Electrocautery. Using electric current to burn off the growth.
Each of these options can effectively eliminate seborrheic keratosis, and our dermatologists will help determine the best treatment based on your specific needs.
