Seborrheic keratoses are benign (non-cancerous) skin growths that are often associated with aging. These appear as oval, bumpy spots on the skin that may resemble warts or moles. They are usually tan or brown in color. These lesions appear to be stuck on the skin like a droplet of wax. Usually, they are painless. However, they may become scaly and dry which can lead to itching or irritation of the affected skin. Occasionally, scratching or rubbing will make these lesions flake off.
Keeping your skin moisturized throughout the day can help reduce itching. Don’t scratch or pick a seborrheic keratosis since that may lead to further inflammation or bleeding. You may have irritated or unsightly keratoses taken off with liquid nitrogen or other minimally invasive removal methods such as shave removal, curettage, or laser therapy.
There is no known way to prevent this skin condition, it appears to be hereditary. The most troublesome aspect of seborrheic keratoses is that they may resemble melanoma or squamous cell skin cancer. It’s a good idea to have a dermatologist examine any suspicious brown spots on your skin to determine if they should be biopsied to rule out cancer.
