L20-L30: Dermatitis and eczema

Dermatitis and eczema encompass a group of skin conditions that trigger inflammation of the skin. These conditions are generally characterized by itchy, red, and dry skin resulting from various causes including allergic reactions, irritants, genetic predisposition, or certain diseases. Dermatitis can be either an acute or chronic condition, affecting any part of the body, including the hands, feet, elbows, and the face. While these conditions are not infectious or contagious, they may significantly impact a person's comfort, self-esteem, and overall quality of life. The manifestation and severity of symptoms can fluctuate over time, often having periods of flare-ups followed by remissions. The skin inflammation in these conditions is primarily driven by an overactive immune system response, leading to excessive inflammation that damages the skin's barrier, leading to dryness and itchiness. Although dermatitis and eczema can affect individuals of all ages, they are notably more common in children.
