<p><strong>What is Actinic Keratosis?</strong></p>
<p><strong>Definition of Actinic Keratosis</strong></p>
<p>Actinic keratosis is a premalignant condition that causes scaly, thick, or crusty patches of skin. This is due to prolonged and excessive exposure to ultraviolet rays of sun. It is predominant across commonly exposed parts of body like ears, face, chest, forearms, back of hands, lips, neck, and bald patches on scalp. Actinic keratosis is same as senile keratosis or solar keratosis.</p>
<p>Actinic keratosis starts as a small spot or patch on your skin. It is flat and scaly at first. Sometimes it disappears only to reappear again. Slowly it grows into a dry, thick, and rough wart. This enlarges and develops over many years. Actinic keratosis is more prevalent in elderly people as it develops over many years.</p>
<p>An actinic keratosis is normally two to six millimeters in size. It is pinkish or reddish in color with a light or dark shade. Sometimes it is similar to your skin color. It occurs mostly among fair-skinned people. Asians, African-Americans, Hispanics, and others with darker skin are not as susceptible.</p>
<p><strong>Diagnosis of Actinic Keratosis</strong></p>
<p>A thorough physical examination can diagnose actinic keratosis. If keratosis is too thick or large, a biopsy is essential to confirm if it is keratosis or skin cancer. Actinic keratosis is similar to seborrheic keratosis, another type of skin lesion. However, this is not caused due to sun exposure and does not develop into skin cancer.</p>
