Seborrhoeic Keratosis

What is Seborrhoeic Keratosis?

Seborrhoeic keratoses are common benign (non-cancerous) skin lesions that accumulate as we get older.

They are usually brown but can be tan or pink. They are often a bit scaly and can sometimes be itchy or catch on clothing or jewellery.

Generally, seborrhoiec keratoses have a “stuck-on” appearance.

Other names for these lesions are “brown warts” or “age warts”. Seborrhoeic keratoses are not at all related to viral warts (HPV – human papilloma virus) and are not contagious. They may, however, run in families.

Seborrhoiec keratoses do not cause harm and can be left alone. Treatment is offered if they are causing a cosmetic concern, or are becoming recurrently irritated. Sometimes, a skin biopsy will be recommended to rule out skin cancer if the appearance is unusual.

If you, or someone you know, have a lump or bump on your skin that is new, growing or changing, we recommend it be assessed to rule out skin cancer.
