Introduction
During seasonal changes, fluctuations in temperature and humidity may affect the moisture balance of the skin on the palms, potentially causing obstruction of sweat gland secretion. This can lead to accumulation of sweat within the palm skin, resulting in dyshidrotic eczema, which is usually accompanied by mild itching or prickling sensations. It is recommended to keep hands dry and avoid prolonged contact with water or damp environments. Chronic infections of the palms may trigger eczema.
In general, the development of dyshidrotic eczema (pompholyx) on the palms may be caused by factors such as seasonal changes, excessive sweating, fungal infections, allergic dermatitis, and eczema. If discomfort occurs, it is recommended to seek medical attention promptly. Specific analyses are as follows:
1. Seasonal Changes
During seasonal transitions, changes in temperature and humidity can affect the moisture balance of the skin on the palms, potentially leading to impaired sweat gland excretion. This may cause sweat to accumulate within the skin, resulting in dyshidrotic eczema, usually accompanied by mild itching or a prickling sensation. It is advisable to keep hands dry and avoid prolonged contact with water or damp environments.
2. Excessive Sweating
When the palms sweat excessively, sweat may block the sweat ducts, causing sweat to accumulate beneath the skin and form blisters characteristic of dyshidrotic eczema, which may be accompanied by itching or a burning sensation. It is recommended to keep the palms dry and avoid staying in hot, humid environments for extended periods.
3. Fungal Infection
Fungal infection of the palms may compromise the skin barrier, leading to impaired sweat excretion and the formation of dyshidrotic eczema. This condition is often accompanied by symptoms such as skin scaling and cracking. It is recommended to follow medical advice and use antifungal medications such as flucytosine tablets, nystatin tablets, or fluconazole capsules for treatment.
4. Allergic Dermatitis
Exposure of the palms to allergens—such as chemicals, metals, or cosmetics—may trigger allergic dermatitis, which in turn can lead to the development of dyshidrotic eczema, along with symptoms like itching and stinging. It is advisable to use medications such as betamethasone tablets, triamcinolone acetonide tablets, or hydrocortisone tablets under medical supervision.
5. Eczema
Chronic inflammation of the palms may lead to eczema, a chronic inflammatory skin condition that can manifest as dyshidrotic eczema, accompanied by symptoms such as dryness and itching. It is recommended to use medications such as desonide cream, fexofenadine hydrochloride tablets, or erythromycin ointment as directed by a physician.
In daily life, maintaining proper hygiene, bathing regularly, and changing clothes frequently are important measures to help prevent the occurrence of such conditions.
