Clinical information

• Eczema is not a one-size-fits-all diagnosis. It includes a spectrum a dermatologic conditions such as atopic dermatitis, contact dermatitis (allergic or irritant), and seborrheic dermatitis.
• Triggers vary, and the hallmark symptoms include itchy, red, thickened, scaly, hyperpigmentation, and dry skin. In others, they may also cause brown to purplish skin and small bumps on the arms, legs, and torso, and localized skin eruption or generalized redness and inflammation.
• There are seven types of eczema: atopic dermatitis, seborrheic dermatitis, stasis dermatitis, contact dermatitis, dyshidrotic eczema, and nummular eczema. 
• To diagnose, aside from a physical exam to check the symptoms, practitioners may ask you what may trigger your eczema and have you undergo a patch test. 
• Treatment may include creams, ointment, antibiotics, antihistamines, lotion, and light therapy.
• Environmental allergens, ingested food, harsh chemicals, and cosmetics are frequent causes. Allergic contact dermatitis can stem from exposure to metals, dyes, or cosmetics, while irritant contact dermatitis arises from substances like detergents or solvents.
• Healthcare professionals must assess symptoms carefully and identify potential external or internal triggers, including stress or immune dysfunction.
