Actinic Keratosis
Actinic keratosis (AK), or solar keratosis, or
senile keratosis is a precancerous skin condition
that develops in the skin when exposed to sun,
hydrocarbons, and arsenicals and is more common in
light-skinned people
When the human skin is exposed to the sun, the
UV-B rays from the sun damage the dermis and
epidermis. The epidermis is thinned and damaged
cells calls fibroblasts cause synthesis of
abnormal dermal elastic fibers within the
superficial dermis that give the characteristic
appearance of actinic keratosis.
Actinic keratoses are small, noticeable, red-brown
patches that don’t fade away and have a
characteristic rough texture accompanied by
itching and burning. The lesions are generally
1-3mm in size, occur in clusters, and generally
occur in sun exposed areas like the face, neck,
and hands.
Actinic keratosis has physical characteristics
that allow dermatologists to visually identify
them. If there is any indication of the
possibility of cancer, a skin biopsy is
recommended.
There are several options to treat AK, the
decision on treatment methodology is based on the
nature of the lesion, age and health.
Actinin keratosis can be treated by:
Cryosurgery
Curettage and Electro dissection
Surgical Excision
Dermabrasion
Topical medications
Actinic keratosis can be prevented by avoiding
prolonged exposure to the sun, wearing protective
clothing, using sunscreen lotion and sun glasses
and regular skin self-examination.
