Actinic keratosis

Dr Christophe HSU – dermatologist. Geneva, Switzerland

• These lesions are seen on the sun-exposed skin especially on the face, upper chest, back and forearms. When they are located on the lips, they are called actinic cheilitis.
• They appear as scaly reddish or brown patches on the skin.
• Numerous lesions may occur at the same time.
• If left untreated, they can go on to develop into skin cancers.

Treatment of Pre-malignant growths

• These can easily be destroyed using liquid nitrogen (like dry-ice) or anti-cancer ointments or electrosurgery or excision surgery or laser surgery.
• If you have a skin tumour, it is advisable to check it out with your doctor. He can then advise you on the diagnosis and action to be taken.
