Seborrheic Keratosis

Seborrheic keratosis is a common, benign skin growth that typically appears as a round, flat, or slightly elevated lesion on the skin’s surface. These growths are often brown, black, or beige in color, with a waxy or scaly texture. While seborrheic keratosis is harmless, it can be unsightly or irritating. At Skinsol Dermatology, we offer various treatment options to remove these growths and restore the appearance of your skin.

Causes and Risk Factors

Seborrheic keratosis is caused by the overgrowth of cells in the outer layer of the skin, known as the epidermis. While the exact cause is not fully understood, several factors may contribute to the development of these growths, including:

  • Age: Seborrheic keratosis is more common in individuals over 40, though it can occur at any age.

  • Genetics: A family history of seborrheic keratosis increases the likelihood of developing these growths.

  • Sun exposure: Prolonged exposure to the sun may trigger the formation of seborrheic keratosis, particularly in areas frequently exposed to sunlight.

  • Hormonal changes: Hormonal changes, such as those experienced during pregnancy or with certain medical conditions, can also play a role in their development.

Seborrheic keratosis is not cancerous and does not increase the risk of skin cancer. However, it is important to have growths evaluated to ensure proper diagnosis.

Diagnosis

Diagnosis of seborrheic keratosis is typically made through a visual examination by a trained provider. In some cases, Victoria McKay, PA-C, may perform a biopsy to confirm the diagnosis, especially if the lesion looks unusual or has changed in size or appearance. The diagnosis may include:

  • Visual inspection: A trained dermatologist will examine the growth to determine whether it is consistent with seborrheic keratosis.

  • Skin biopsy: A small sample of the lesion may be taken to rule out other skin conditions, such as skin cancer.

Once diagnosed, treatment can be tailored to the patient’s specific needs and cosmetic goals.

Treatment Options

While seborrheic keratosis is benign and typically does not require treatment, many patients opt for removal due to cosmetic concerns or irritation. Treatment options include:

  • Cryotherapy: This method involves freezing the growth with liquid nitrogen, causing it to fall off after a few days.

  • Curettage: This procedure uses a small surgical instrument to scrape off the growth. It may be combined with electrosurgery to stop bleeding.

  • Laser therapy: Laser treatments can be used to remove seborrheic keratosis, especially in delicate or hard-to-reach areas.

  • Shave excision: This involves shaving off the growth with a scalpel, which is typically used for raised or thicker seborrheic keratoses.

The appropriate treatment will depend on the size, location, and number of seborrheic keratoses, as well as the patient’s preferences.
