chapped skin
Introduction
Introduction The skin is suddenly forced by cold wind and dryness, causing blood circulation, muscle loss, and skin sputum, causing chapped. Hand and foot cleft palate refers to dry and cracked skin of the hands and feet caused by various reasons, accompanied by pain, which can affect daily life and work. The disease is both a concomitant symptom of some skin diseases and an independent skin disease. Hand and foot splitting occurs in autumn and winter. The rash is distributed on the flexor side, the palm, the heel, the lateral aspect of the ankle and other areas where the stratum corneum is thickened or often rubbed. The clinical manifestation is the depth and length of the fissure along the dermatoglyph, and the lesion can be from no feeling. Mild tingling or moderate tenderness, even burning and accompanied by bleeding.
Cause
Cause
1. The corner layer is thicker, especially in the palmar and heel areas, so it is prone to splitting.
2. The palmar skin has no hair follicles and sebaceous glands, so when the temperature is low and the humidity is low in winter, the skin lacking sebum protection is prone to chapped.
3. The above factors, combined with the elderly, ichthyosis and keratosis, cause dry skin, the corner layer is more likely to thicken, and it is more susceptible to disease under the influence of some external factors.
External cause
1. Physical: such as dryness, friction, trauma, etc. can promote the onset.
2. Chemical: Acid, alkali, organic solvent, etc. dissolve sebum, and the skin loses lubrication protection.
3. Biological: If the fungus or the like causes the skin to hyperkeratize, the original protective ability is lost.

The splitting is mostly in the direction of the skin. Skin lesions occur in the skin, the palms, the palms, the heels, the ankles, the feet, etc. The stratum corneum is thick and often rubbed. It occurs mostly in autumn and winter, and the weather is getting warmer and slower. Divided into three degrees according to the degree of cleft palate:
Once: the skin of the affected area is dry and chapped, but only the epidermis is involved, no bleeding, pain, etc.
Second degree: The affected area is dry and the fissure is as deep as the dermis with mild tingling, but no bleeding.
Third degree: The affected area is dry and the fissure is deep to the deep dermis and subcutaneous tissue, often accompanied by bleeding, pain or tenderness.
According to the cracks that occur in the depths of the palm of your hand, the skin is dry, hard, brittle, with reduced elasticity and varying degrees of pain, and it can be diagnosed in autumn and winter.
Diagnosis
Differential diagnosis
1. Hand, foot and ankle: Hand, foot and ankle can also cause cracking pain due to scratching, but the hand, foot and ankle have the following characteristics:
1 often limited to one side of the palm or sputum, finger (toe), rarely limited to the heel.
2 The primary damage is papules and blisters.
3 often itchy, very little pain. Sometimes chapped over the years, not necessarily heavy in summer or summer, but sometimes more severe in summer.
4 often with toe, nails and concomitant.
5 often find fungus in the skin lesions.
It should be pointed out that sometimes the cleft palate can be complicated by both hands and feet, and the two diseases can be mutually causal. According to the survey, the concurrency rate is 30% to 85%.
2. Hand and foot eczema:
Sometimes hand and foot eczema can cause cracking pain due to itching, but when eczema is acute or subacute, the primary damage of erythema, papules, blisters, etc., is often accompanied by itching. If it is chronic, it is often located in the palm of your hand and involves the back of the hands and feet, and it is often accompanied by thick and itchy skin, so the two can be identified. Hand and foot cleft palate can coexist with hand and foot eczema, and the coexistence rate is about 1.4%.
3. Ichthyosis:
Sometimes it is easier to split the hands, feet and feet on the basis of ichthyosis, especially when the ichthyosis is aggravated in the cold season. The concomitant rate of the two diseases is 24% to 47%.
4. Palmoplantar keratosis:
It is a congenital disease that is prone to chapped due to hyperkeratosis. However, palmoplantar keratosis does not necessarily form cleft palate in winter and autumn, and sometimes it can occur all year round. The concomitant rate of the two diseases is 2.4%.
