Actinic Keratosis
Actinic Keratosis 

Actinic Keratosis, also known as sun keratosis or senile keratosis, is a thick, scaly, or crusty patch of skin that is precancerous. Exposure to ultraviolet (UV) light causes the epidermal keratinocyte disease known as actinic keratosis (actin-). Fair-skinned individuals and those who spend a lot of time in the sun are more likely to develop these growths.

They are thought to develop over decades as a result of UV radiation from the sun or indoor tanning beds damaging skin. They may develop into squamous cell carcinoma, a type of skin cancer, if neglected due to their precancerous nature. The danger of developing squamous cell carcinoma from untreated lesions is up to 20%, hence dermatologist treatment is advised.

A biopsy or excision can be taken into consideration for a final diagnosis by histologic examination of the lesional tissue if the clinical examination findings are not typical of Actinic Keratosis and the possibility of in situ or invasive squamous cell carcinoma (SCC) cannot be excluded based solely on the clinical examination.

The Actinic Keratosis Market is anticipated to reach US$ 8,070.0 Mn in 2022 and grow at a CAGR of 4.7% during the projected period (2022-2030).

There are numerous AK therapy options accessible. Field cancerization, or a cluster of AK lesions in one area of the skin, can be treated with photodynamic therapy (PDT). It entails applying a photosensitizer to the skin and then illuminating it with a powerful light source. Topical creams like 5-fluorouracil or imiquimod may need to be applied daily to the affected skin areas over the course of several weeks.

Actinic Keratosis are characterised by a white, scaly plaque of varied thickness and surrounding redness. When felt with a gloved hand, they feel like sandpaper. Skin near the lesion frequently displays signs of sun damage, including deep wrinkles, rough texture, purpura and ecchymoses, dry skin, and scattered telangiectasias.

Notable pigmentary variations include skin that is yellow or pale in hue with regions of hyperpigmentation. A buildup of oncogenic alterations brought on by photoaging causes a proliferation of mutant keratinocytes that can take the form of AKs or other neoplastic growths. It is possible to get several AKs in one area of the skin after years of sun damage. Field cancerization is the name given to this disorder.
