What condition is characterized by red, itchy patches and often occurs in childhood?

The condition characterized by red, itchy patches that often occurs in childhood is eczema, also known as atopic dermatitis. Eczema is a chronic inflammatory skin condition that typically appears in early childhood and can continue into adolescence or adulthood. It presents as dry, itchy skin, which can lead to scratching, further irritation, and potential secondary infections. The appearance of red, inflamed patches is a hallmark symptom, and eczema can be exacerbated by environmental factors such as allergens or irritants.

In contrast, psoriasis is an auto-immune condition that can also cause red patches and scaling, but it often manifests as thick, silver scales and is less common in young children. Acne, on the other hand, is primarily associated with hormonal changes during adolescence and typically involves the presence of pimples, blackheads, and cysts rather than itchiness and patches. Rosacea usually affects adults and is characterized by facial redness and visible blood vessels, rather than the patchy, itchy skin seen in eczema.
