Seborrheic Warts
What are seborrheic warts?
Seborrheic warts, also known as seborrheic keratosis, are common, non-cancerous growths on the skin. Seborrheic keratosis typically appears to be pale, black, or brown growths on the back, shoulders, scalp, chest or face. These warts may look scaly, waxy and slightly raised. They are harmless and not contagious.
The cause of seborrheic warts is unknown; however, they tend to run in the family. Therefore, genes play a massive role in the development of the condition. Sun exposure may also contribute to the development of seborrheic warts.
The condition is characterised by are:
- Round or oval-shaped
- Range in colour from light tan to brown or black
- Flat or slightly raised with a scaly surface
- Range in size from small to more than 2.5 cm across
- May be itchy
Seek medical attention when warts grow over a short period, when they become irritated or bleed due to the rubbing of clothes against them, or when you notice suspicious changes in your skin, such as sores and bleeding.
How are seborrheic warts treated?
In most cases, seborrheic warts do not require treatment. However, your doctor may deem it fit to remove warts if they have a suspicious appearance, bleed, become irritated or cause physical and emotional discomfort.
Dr Zinzi Limba may recommend one of the following procedures to treat seborrheic warts:
Cryosurgery
Also called cryotherapy, it is a procedure that involves the dermatologist applying liquid nitrogen to the wart to freeze it. It will then fall off in a few days.
Ablation
This is a procedure that involves vapouring the growth with a laser.
Electrocautery
Also known as electrosurgery, this procedure involves using an electric current to cauterise (burn) warts. Electrocautery may be used alongside the curettage procedure.
Curettage
This procedure involves the dermatologist using a curette, a spoon-shaped instrument to scrape and remove seborrheic warts. Curettage may be done after the electrocautery procedure.
