Actinic Keratosis is more habitual to fair-skinned people that are generally exposed to sun, as their pigment is not very preventive. It usually is conducted by solar damage. Since some of these pre-cancers futhers to squamous cell carcinoma. People who made visible their skin to sun normally, mainly without wearing sunscreen, are more probably to ripen actinic keratoses. They are also much general in people having red hair and freckles. AKs used to be more visible in the elderly, they are now seen more often in younger people resulting to changes in the environmental conditions and lifestyles. Actinic keratoses are ingenerated by recurent and prolonged exposure to the sun’s ultraviolet rays. Ultraviolet B (UVB) radiation causes the cells on the surface of the skin to suffer mutations that can cause abnormalities in certain genes. One particular gene which is affected is TP53, a gene that curtail tumors. Actinic keratosis site chiefly ranges between 2 to 6 millimeters, somtimes may be dark or light, tan, pink, red, a combination of all these, or the same pigment of one’s skin.

Patients may mature multiple lesions within a single anatomic area to the extent that the lesions collide and produce confluent AK over a relatively large area. Variants may be broeratosewn (pigmented AK), lichen planus–like, or have exaggerated hyperkeratosis, producing a hornlike projection above the skin surface known as a cutaneous horn. Although rarely seen today, arsenical ks usually occur on patients who were at some time in their live exposed to arsenic, either contained in medication or from an industrial or environmental source. These piles normally on the palms, soles, and inner surfaces of the finger and toes, and then grows and thicken, sometimes increasing in number.

Causes of Actinic Keratosis

Common causes of Actinic Keratosis

• Light complexions.
• Sun exposure( Ultraviolet B)
• Squamous cell carcinoma.
• Abnormalities in certain genes.
• Chemotherapy.
• Chronic leukemia.

Symptoms of Actinic Keratosis

Common Symptoms of Actinic Keratosis

• Dry textured skin lesion.
• Macule or patch and growth on the skin.
• Have a rough texture.
• Itch, burn, or sting.
• Lesions on your skin.

Treatment of Actinic Keratosis

The therapy for actinic keratoses expects upon the number and size of the lesions. An actinic keratosis is generally dealt by liquid-nitrogen cryotherapy. In this therapy, the treatment selectively tears down actinic keratoses, causing little damage to surrounding normal skin, although some lump sometimes occurs. The excision of actinic keratoses is occasionally a useful and definitive treatment in selected lesions. Common Treatment of Actinic Keratosis

• Cryosurgery
• Photodynamic therapy is involves injecting a chemical into the bloodstream.
• Electrocautery is burning off AKs.
• Useful treatment is the application of 5-fluorouracil (5-FU).  The medication is applied on the keratoses for three to six weeks.  5-FU destroys sun-damaged skin cells.
