Which feature describes dyshidrotic eczema vesicles?

• A. Vesicular lesions on lateral aspects of fingers
• B. Lesions on face
• C. Patches on scalp
• D. Lesions on soles only

Answer: (A)

The key feature being tested is where dyshidrotic eczema vesicles typically appear. Dyshidrotic eczema, or pompholyx, presents with small, deep, pruritic vesicles most characteristically on the lateral aspects of the fingers and, to a lesser extent, the palms. This finger-side distribution is what sets it apart from other dermatitis patterns. If vesicles were on the face or scalp, that would align more with other conditions such as atopic dermatitis affecting the face or seborrheic changes on the scalp. Vesicles confined to the soles are less characteristic for dyshidrotic eczema, which more reliably involves the hands (and can involve palms and sometimes soles, but not exclusively). Thus, vesicles on the lateral aspects of the fingers best describe the dyshidrotic pattern.
