Frequently asked questions
The exact cause of seborrheic keratosis is unknown, but it is thought to be related to age, genetics, and sun exposure. These growths tend to be more common in older individuals, and there may be a genetic component to their development. Additionally, exposure to ultraviolet (UV) radiation from the sun or tanning beds may increase the risk of developing seborrheic keratosis.
Seborrheic keratosis typically presents as a raised, waxy, and scaly growth on the skin, ranging in color from tan to brown to black. The growth may be small or large, and may have a smooth or rough surface. In some cases, the growth may itch or become irritated.
Seborrheic keratosis is typically diagnosed based on its appearance. A dermatologist or other healthcare provider may perform a physical exam and evaluate the growth to determine if it is seborrheic keratosis or another skin condition. In some cases, a biopsy may be performed to confirm the diagnosis.
