Actinic keratosis

Actinic keratosis, also referred to as solar keratosis, is a common premalignant cutaneous neoplasm that arises within the epidermis due to cumulative ultraviolet radiation exposure The condition predominantly affects fair-skinned, older, or immunocompromised individuals across chronically sun-exposed anatomical sites such as the face, scalp, ears, forearms, and dorsal hands Clinically, lesions present as rough, gritty, erythematous, or hyperkeratotic papules and plaques Pathophysiologically, it...

Actinic keratosis, also referred to as solar keratosis, is a common premalignant cutaneous neoplasm that arises within the epidermis due to cumulative ultraviolet radiation exposure

The condition predominantly affects fair-skinned, older, or immunocompromised individuals across chronically sun-exposed anatomical sites such as the face, scalp, ears, forearms, and dorsal hands

Clinically, lesions present as rough, gritty, erythematous, or hyperkeratotic papules and plaques

Clinically, lesions present as rough, gritty, erythematous, or hyperkeratotic papules and plaques

Pathophysiologically, it is characterized by atypical keratinocyte proliferation, nuclear pleomorphism, and architectural disorganization within the epidermis, carrying an intrinsic potential to progress to invasive cutaneous squamous cell carcinoma
