There are two types of Keratoses which are:
• Actinic keratoses, also known as solar keratoses, are dry scaly patches of skin caused by damage from years of sun exposure. The patches can be pink, red or brown in colour, and can vary in size from a few millimetres to a few centimetres across. The skin in affected areas can sometimes become very thick, and occasionally the patches can look like small horns or spikes.
• Seborrheic keratosis is a type of skin growth. They can be unsightly, but the growths are not harmful. However, in some cases a seborrheic keratosis can be difficult to distinguish from melanoma, a very serious type of skin cancer.
HOW IS KERATOSIS DIAGNOSED?
A dermatologist will often be able to diagnose keratosis by eye. If there’s any uncertainty, they'll likely remove part or all of the growth. This is called a skin biopsy. The doctor may use a bright light or magnifying lens to look for growths, moles, or lesions. The scalp is examined by parting the hair.
HOW IS KERATOSIS TREATED?
In many cases keratosis does not need treatment. However, a doctor may decide to remove any growths that have a suspicious appearance or cause physical or emotional discomfort.Treatment options for keratosis include surgery, cryotherapy, dermabrasion, topical medications, chemical peels and photodynamic therapy (PDT).
