Where are the vesicles associated with dyshidrotic eczema most commonly found?

Dyshidrotic eczema, also known as pompholyx, is characterized by the presence of small, itchy vesicles that typically appear on the hands and feet. Among the choices, the palms are the most common site for these vesicles. This condition is often triggered by factors such as stress, heat, and humidity, leading to the formation of blisters that can be very uncomfortable.

The vesicles are distinct in that they often appear on the palms, fingers, and sometimes the soles of the feet, with eruptions being more prominent on the sides of the fingers and along the palms themselves. The vesicular lesions can lead to significant itching, which may result in scratching and secondary infections.

In contrast, the other areas listed—such as the axillae, intertriginous areas, and upper back—are not typical locations for dyshidrotic eczema. While these regions can have various dermatoses due to friction, moisture, or irritation (such as intertrigo or other types of eczema), they are not characterized by the specific vesicular pattern seen in dyshidrotic eczema. Thus, the palm's involvement is a hallmark feature of this condition, underscoring its distinction from other skin conditions.
