1. The occurrence of dyshidrotic eczema has obvious seasonality. It often occurs at the turn of spring and summer and heals itself in winter. It mainly occurs in young people.

2. It is now generally believed to be a skin eczema-like reaction, which is related to factors such as mental stress, excessive sweating of hands and feet, fungal infection and allergic reaction.

3. Symmetrical occurrence on the palms and soles, deep in small blisters, occurring in batches, with tense blister walls, millet to rice-grain size, hemispherical and slightly raised above the skin surface, visible on the palms, sides and fingertips, with no inflammatory response.

For those with obvious itching, corticosteroid preparations such as triamcinolone, compound Conal Cream, and chlorpromazine can be used. If the main symptoms are erythema, desquamation, and chapped skin, you can apply 10% urea cream, silicone cream, vitamin E cream, or salicylic acid ointment externally 1 to 2 times a month. Systemic treatment can be with antihistamines, vitamins B1, B2, A, and E. If the number of rashes is large and the subjective symptoms are obvious, a short course of oral corticosteroids such as prednisone can be taken, 10 mg each time, 3 times a day.
