Raised skin edges

Introduction The edge of the skin is mainly caused by dry and rough skin, and the edge of the dander is slightly tilted. It looks like snake skin or sweat pores. It is blocked by particles and can't grow hair. The skin is grayish brown scales and deep and heavy. The whole body is most common in ichthyosis. The cold and dry season is aggravated, and the warm and humid season is relieved. Easy to relapse. Multiple lines of genetic factors cause abnormal proliferation and differentiation of epidermal cells, resulting in increased cell proliferation and/or decreased cell shedding. The disease is mostly caused by children, mainly characterized by dry and rough skin on the extremities or trunk of the extremities, accompanied by rhomboid or polygonal scales, and the appearance is like fish scales or snakeskin.

Cause

Genetic, neurological factors, chemical endocrine, infectious factors or external factors can cause skin edges to rise, often caused by a combination of factors.

1. Carefully ask the relevant medical history and collect relevant clinical data.

2, closely examine the patient, clearly understand the patient's clinical symptoms, mainly to understand the changes in the skin.

3, appropriate physical examination of the patient, a preliminary understanding of the morphological changes of the various organs of the patient.

4. Perform relevant equipment examinations on patients and conduct laboratory tests as appropriate.

5, comprehensive consideration of various inspection results, combined with the clinical symptoms of various organ damage, and finally draw a corresponding diagnosis.

Differential diagnosis

1, ichthyosis vulgaris: mainly in the extremities of the limbs and the trunk of the dry brown diamond, or polygonal scaly, the upper arm and thigh extension often have obvious follicular keratotic papules, palm toe involvement, the incidence is very high, The keratinized scaly is caused by the accumulation of several layers of keratinocytes, which is more than a few months after birth. It is the heaviest at about 5 years old, and the symptoms may be alleviated after puberty, but it is aggravated with age and treatment.

2, sexual chain cryptic ichthyosis: can occur after birth or infants, skin lesions large and significantly yellowish brown or dirty black, large scales of fish scales, dry and rough skin, often throughout the body. Axillary fossa and elbow fossa can also be affected; the back of the abdomen is particularly heavy. If the face is affected, it is limited to the front of the ear and the face. The flank of the follicle does not occur on the side. The skin at the palm is normal. The lesion does not decrease with age. Sometimes it is instead Weight gain.

3, epidermis loosening hyperkeratosis ichthyosis, also known as bullous congenital ichthyosis-like erythroderma: an autosomal dominant genetic disease with high distortion rate, clinically rare, after birth or several months after birth Generalized and limited damage. When the generalized person is born, there is a thick layer of scales in the whole body, which will fall off after birth, and there will be generalized flushing and scale stripping scales, which will show the erythema of the face, which can gradually disappear, and the thicker scales can be regenerated. The limit of the situation is only in the flexor and wrinkled parts of the limbs, and there may be thicker scaly horny slices.

4, lamellar ichthyosis is autosomal recessive, after the birth of the whole body is a wide layer of human cotton gelatinous membrane, tightly wrapped. More eyelids and lip valgus, the film fell off after a few days, the skin is widely diffuse flushing, with grayish white or taupe polygon or diamond-shaped large scales, central fixation, edge free, often symmetrical in the body, with limbs The side, elbow socket, armpit and vulva are more obvious. The palm of the hand is hyperkeratotic, the nail and hair are overgrowth, the disease course is slow, and it can survive. The erythroderma can be alleviated in adulthood, but the scales still exist.
