What is keratosis?

1. A skin infection caused by bacteria

2. A skin condition marked by a horny growth

3. A type of skin cancer

4. Allergic reaction on the skin

The correct answer is: A skin condition marked by a horny growth

Keratosis refers to a skin condition characterized by the growth of keratin on the skin surface, resulting in the formation of thick, hardened patches or horns. This condition occurs due to an overproduction of keratin, which is a protein that helps protect the skin. Keratosis can manifest in various forms, such as seborrheic keratosis or actinic keratosis, and is typically benign. By describing keratosis as a condition marked by a horny growth, it accurately captures the essence of what this term signifies in dermatological terms, focusing on the physical appearance and underlying biological process involved. In contrast, describing keratosis as a skin infection or a type of skin cancer does not provide an accurate representation of the condition. Keratosis is not infectious, nor is it inherently cancerous, although some forms can have a potential link to cancer if they develop from damaged skin in sun-exposed areas. An allergic reaction on the skin focuses more on the immune response to allergens, which is unrelated to the growth of keratin associated with keratosis. This clarity helps distinguish keratosis from other skin conditions and solidifies the understanding of its specific characteristics.
