Differences between vesicular tinea manuum and dyshidrotic eczema

Differences between vesicular tinea manuum and dyshidrotic eczema: 1. From the perspective of etiology, vesicular tinea manuum is primarily caused by fungal infection and is contagious, commonly spreading through direct contact; whereas the cause of dyshidrotic eczema is relatively complex, possibly related to factors such as mental stress, excessive sweating of hands and feet, and allergic reactions. The exact etiology remains incompletely understood. 2. Regarding affected areas and symptoms, vesicular tinea manuum typically occurs on the palms and the areas near the fingers, presenting with clear, fluid-filled vesicles, often accompanied by scaling and itching; in contrast, dyshidrotic eczema commonly appears on the fingers, between the fingers, and on the palms and soles, characterized by small vesicles, mostly without fluid discharge, frequently accompanied by varying degrees of itching and a burning sensation. 3. The disease course also differs between the two conditions. Vesicular tinea manuum tends to occur more frequently in summer, with milder symptoms during winter, and it does not resolve spontaneously; dyshidrotic eczema, however, exhibits a certain seasonality, often starting in late spring to early summer, worsening during summer, and possibly resolving spontaneously in winter. For patients experiencing related symptoms, timely medical consultation is recommended.
