Which condition is characterized by an excessive production of skin cells?

1. Contact dermatitis

2. Psoriasis

3. Eczema

4. Asteatosis

The correct answer is: Psoriasis

Psoriasis is a condition characterized by an excessive production of skin cells, leading to the formation of thick, silvery scales and dry, red patches that can be itchy and sometimes painful. This occurs because the skin cells regenerate at an accelerated rate – roughly every three to four days – instead of the normal cycle of about 28 days. This rapid turnover results in a buildup of cells on the surface of the skin, which is the hallmark of psoriasis. In contrast, contact dermatitis and eczema primarily involve inflammation due to various irritants or allergens, which do not necessarily lead to the excessive buildup of skin cells. Asteatosis, which refers to dry skin due to a lack of oil, also does not involve the accelerated production of skin cells. Therefore, psoriasis is uniquely associated with this condition of hyperproliferation of skin cells, making it the correct answer.
