Introduction
Excessive hand sweating and small red spots on the palms are often caused by factors such as dyshidrotic eczema, tinea manuum (hand fungus), or eczema, and appropriate treatment should be selected under medical guidance. Additionally, they may also result from contact dermatitis, syphilitic rash, or palmoplantar pustulosis, which require prompt medical attention. In daily life, it is important to maintain clean, dry hands and manage diet appropriately.
Excessive hand sweating accompanied by small red spots on the palms is often caused by conditions such as dyshidrotic eczema, tinea manuum (hand fungus), or eczema. Appropriate treatment should be selected under medical guidance. Specific analyses are as follows:
1. Dyshidrotic Eczema
Dyshidrotic eczema is characterized by deep-seated papules and vesicles within the epidermis, ranging in size from pinhead to grain-like, commonly occurring on the palms. It is frequently associated with excessive hand sweating. Localized erythema and pain may also occur. Under a doctor's guidance, topical application of triamcinolone urea cream may be used.
2. Tinea Manuum (Hand Fungus)
After sweating, the palms become more susceptible to bacterial growth, increasing the risk of developing tinea manuum. This condition typically presents with tiny vesicles resembling pinheads and significant itching. Treatment should be conducted under medical supervision using antifungal medications such as compound clotrimazole cream, bifonazole solution, or compound povidone-iodine lotion.
3. Eczema
During summer, increased hand perspiration combined with inadequate hygiene may lead to eczema, causing skin irritation and inflammatory responses manifesting as small red spots and papules. Under medical advice, treatments may include hydrocortisone cream, levocetirizine hydrochloride tablets, or ebastine tablets.
In addition, other possible causes include contact dermatitis, syphilitic rash, or palmoplantar pustulosis, all of which require timely medical evaluation and management. It is important to maintain clean, dry hands in daily life, manage diet appropriately, and avoid spicy foods and allergenic or inflammatory-triggering foods.
