Introduction
Hand fissures may result from physiological factors or pathological conditions such as dishydrotic eczema or tinea manuum. Localized skin dryness or frequent contact with alkaline cleaning products can damage the skin's sebum membrane and stratum corneum, leading to cracking of the hands. Proper hand care should be maintained, and exposure to alkaline substances should be avoided. Besides these causes, hand fissures may also be caused by ichthyosis vulgaris.
Hand fissures may be caused by physiological factors, or by pathological conditions such as fissured eczema or tinea manuum. The specific details are as follows:
I. Physiological Factors
Fissures can occur when the local skin is dry or frequently exposed to alkaline cleaning products, damaging the skin's protective lipid film and stratum corneum. Proper hand care should be maintained, and the use of alkaline substances should be avoided.
II. Pathological Factors
1. Fissured Eczema
This commonly occurs in areas with a thick stratum corneum, such as the palms and soles, especially during winter when skin tends to be dry. Symptoms include dry skin and fine cracks. Treatment may include antihistamines such as loratadine tablets or cetirizine hydrochloride tablets under medical supervision.
2. Tinea Manuum (Fungal Infection of the Hand)
If a person has close contact with individuals infected with fungi or remains in hot, humid environments for prolonged periods, fungal infection may develop, leading to hand fissures. Treatment options under medical guidance include topical antifungals such as compound ketoconazole ointment, ketoconazole cream, or terbinafine hydrochloride cream.
In addition to the above causes, hand fissures may also result from common ichthyosis. If any discomfort occurs, patients should seek timely medical attention. Adequate rest is recommended, and lifting heavy objects should be avoided.
