Small blisters appearing on the hands that turn yellow and peel may be caused by conditions such as tinea manuum (fungal infection of the hands), eczema, or palmoplantar pustulosis, among other reasons. Treatment depends on the specific underlying cause. Detailed analysis is as follows:

1. Tinea Manuum

In patients with tinea manuum, fungal infection of the skin on the hands can lead to symptoms including blisters, scaling, and itching. Treatment should follow medical advice and typically involves antifungal medications such as terbinafine or itraconazole. For cases with明显 skin thickening, salicylic acid may be used in combination to remove excess keratin.

2. Eczema

Eczema may develop due to triggers such as irritants or weakened immunity, causing blisters and itching on the fingers, followed by peeling. Localized itching can sometimes become severe and interfere with sleep. Treatment may include topical applications such as mometasone furoate cream, hydrocortisone butyrate cream, or other prescribed medications.

3. Palmoplantar Pustulosis

This condition primarily presents as recurrent sterile blisters on the palms and soles, some of which may become pus-filled. Treatment, based on a doctor’s recommendation, may include topical medications such as budesonide ointment, coal tar ointment, or tretinoin ointment. In more severe cases, oral medications like prednisone or cyclosporine may be prescribed to modulate the immune response.

Besides the above, similar symptoms may also result from dyshidrotic eczema (pompholyx), fungal infections, or allergic dermatitis. It is recommended that patients seek medical evaluation at a hospital to determine the exact cause and receive timely treatment.
