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 characterized by an excessive production of skin cells, leading to the rapid turnover of skin cells that results in thick, red, scaly patches. This condition occurs due to an accelerated life cycle of skin cells, where the skin cells regenerate at an unusually fast rate. While normal skin replaces cells every 28 to 30 days, in psoriasis, this process can occur in just a few days, contributing to the buildup and the formation of plaques on the skin's surface. Other conditions listed do not primarily involve excessive skin cell production. For example, contact dermatitis is a reaction to irritants or allergens, causing inflammation and irritation rather than an increase in skin cell turnover. Eczema is characterized by inflammation and itchiness, often related to an allergic reaction but is not defined by rapid skin cell production. Asteatosis involves dry, scaly skin due to a lack of oil, not an increase in cell production. Understanding these distinctions is crucial for recognizing and properly managing different skin conditions.
