Benign Skin Tumor
Seborrheic keratosis are thick growths that may:
- Look yellow, tan, brown, white, or black
- Be waxy or look like warts
- Be round, flat, or oval in shape
- Be itchy when irritated by clothing or jewelry
- Appear anywhere on the skin
Some people have one lesion, but it is more common to have many.
It may be hard to detect the difference between seborrheic keratosis and melanoma , a potentially fatal skin cancer. It is important to see visit the doctor anytime new or changing skin lesions are noticed.
Your doctor will ask about your symptoms and medical history. A physical exam will be done. Your doctor can usually make a diagnosis upon examination of the skin growth. You may need further testing, such as a skin biopsy , to rule out other skin conditions.

Seborrheic keratoses do not pose a health threat. The best course of action may be to leave them alone. If they itch or become irritated, or if they are unsightly, they can be removed.
Treatment options include:
Topical corticosteroids may be advised.
If a decision is made to remove the seborrheic keratoses, surgical options include:
- Freezing the growth, which falls off a few days later
- Removal with a razor or scalpel
- Laser surgery to burn the growth off
