Keratosis

A  keratosis is a common benign skin growth, similar to a mole. Most people will have at least one in their lifetime. They tend to appear in mid-adulthood and their frequency increases with age. They are harmless .

Skin growths like  keratosis are sometimes also called epidermal tumours. That doesn’t mean they’re cancer, though. Technically, moles and warts are also epidermal tumours. It just means they are clusters of extra cells on the epiderma, which is the outer layer of the skin. Thre are 2 types of Keratosis, Seborrheic and Actinic. 

Keratosis are roundish or oval-shaped patches on the skin with a “stuck on” appearance. They are sometimes described as waxy or scaly. Generally are raised above the skin and even when they are flat you can feel them with your finger. Keratosis are usually brown, but can also be black or tan, and less often, pink, yellow or white.

Keratosis are characterised by keratin on the surface — the same fibrous protein that fingernails, hooves, and horns are made of. This causes the textural details that often distinguish the growths. Sometimes it looks like small bubbles or cysts within the growth. Sometimes it looks scabby or wart-like.

How will they be removed?

Here at Persona we have options for removing your keratosis:

• Cryotherapy. Your Medical practitioner will numb the skin and then use liquid nitrogen to freeze the growth. This will cause it to fall off within a few days or weeks. Cryotherapy is a common choice when the diagnosis is clear and there is no need to preserve a sample of the growth for biopsy. One possible side effect is that the skin where the growth was will lose some of its pigment and look lighter.
• Electrodessication/Curettage. Your Medical practitioner will numb the skin and then use a targeted electro-current to burn the keratosis. They use a surgical instrument called a curette to scrape away the remains of the growth. Electrodessication and curettage are also sometimes used individually. The risk of scarring is generally low with both methods, but there is some wound care involved afterward.
• Shave Excision. This is the preferred method when your Medical practitioner wants to preserve a sample of the growth to analyse in the lab. After numbing the skin, they will carefully shave off the growth and smooth the skin underneath with a surgical curette. Then they’ll send the shaved growth to the lab for analysis.
• Laser Therapy. Lasers offer an alternative to surgery by burning the growth, sterilising the wound and sealing the tissue all at once. Laser therapy is quick, but the wound will be sore for a while afterward. Lasers are associated with good cosmetic results.
