Which skin condition is characterized by small fluid-filled blisters?

• A. Vesicular eczema
• B. Psoriasis
• C. Contact dermatitis
• D. Atopic dermatitis

Answer: (A)

Vesicular eczema is characterized by the presence of small fluid-filled blisters, known as vesicles. This type of eczema typically involves an inflammatory response in the skin that leads to the formation of these vesicles, which can break open and weep, potentially creating a crust. The condition often results from contact with irritants or allergens, leading to an immune-mediated reaction.

In contrast, psoriasis is characterized by thick, scaly patches usually involving red, raised areas on the skin, rather than blisters. Contact dermatitis can also cause inflammation and irritation, but it does not primarily present with vesicular formations; instead, it may cause redness and itching, sometimes leading to dry patches but not specifically small fluid-filled blisters. Atopic dermatitis, while it may have vesicular manifestations in some cases, typically presents with dry, itchy skin and thickened areas rather than the distinct vesicular lesions seen in vesicular eczema.
