Expansive striae

Introduction Streae atrophicae (Striae atrophicae), also known as striae distensae, white line (lineae albicantens), occurs during pregnancy called striae gravidarum, which is the variability of dermal elastic fiber rupture and skin overextension. Chinese medicine believes that the disease is caused by insufficient congenital endowment or loss of blood and skin. Atrophic pattern refers to the formation of a cord-like skin atrophy due to obesity, pregnancy, edema and the like. Diagnostic points: occur at any age, more common in adolescence, young people gain too much weight and pregnant women. Early lesions were strip-shaped reddish-brown, slightly elevated. The old man has a white shrinking pattern. No symptoms. According to different situations, there is no part, pregnant girls in the abdomen. During puberty, it occurs in the medial, hip and back waist. It occurs in the ankle, groin and other wrinkles due to the taking of corticosteroids.

Cause

Due to endocrine changes, excessive adrenal short corticosteroids, increased fibrin decomposition, collagen fibers, elastic fibers, and inhibition of fibroblast function, skin hypertonia caused by skin elasticity, elastic fibers break and cause disease. In addition, some people think that special infections (such as tuberculosis) or tumors can also cause shrinkage lines, which is a poisoning relationship. The dermis elastic fiber is broken and denatured, and the skin is over-extended and the atrophy changes.

Due to the breakage of the elastic fibers of the dermis layer. The causes of elastic fiber breakage are:

First, the rapid development of puberty, the formation of elastic fibers is less than the development speed of the body, the elastic fibers are torn.

Second, excessive obesity, elastic fibers are torn.

Third, some endocrine diseases, excessive secretion of glucocorticoids, broken and broken elastic fibers (glucocorticoids can promote the decomposition of protein fibers).

Fourth, some glucocorticoid drugs are taken orally, and the elastic fibers are broken down and broken.

5. Long-term external use of hormones for external use, the elastic fibers are broken down and broken.

6. Breaking decomposition of elastic fibers caused by various other factors.

The shrinking lines occur in the inner thighs, the waist and abdomen, etc., and the strips of the watermelon pattern, which are alternately distributed in red and light white, generally have multiple strips, which are not painful or itchy. According to the onset of puberty, the location of the disease, clinical manifestations, the disease is easy to diagnose. The disease generally has no major impact on health, so no special treatment is needed.

Adolescent shrinkage lines are not only for women but also for men. It is a physiological phenomenon in the development of healthy boys and girls. The time of appearance of atrophic lines in adolescence is generally greater after the pubic hair grows, and most of them appear simultaneously with "acne". Most of the males appear in the inner and outer thighs of the thighs, while the females mainly occur in the lower abdomen, thighs, buttocks, breasts, and the like. When the shrinkage lines start, they are slightly higher than the leather surface, and then gradually become irregularly striped or belt-like skin depressions arranged in parallel. The skin of the depressions becomes thinner and the surface is bright, up to several centimeters and about 1 cm wide. The color is mostly reddish or purple. After half a year to two years, most of the light-colored traces that are close to color and skin color may not fade for a long time, and some will gradually fade and disappear after adolescence. The atrophic pattern does not hurt or itch, nor any other discomfort, and has no effect on health.

Differential diagnosis

Obesity: As the volume of bones and muscles or fat increases too fast, beyond the prolonged speed of the skin, the elastic fibers of the dermis are pulled apart to form this pattern. People who are overweight can see this situation, and many people in development can appear even if they are not very fat. Even if the weight loss succeeded in restoring the original body shape, the growth pattern could not be eliminated. It began to be red, gradually darkened over time, and finally turned into white stripes.

Abdominal skin plum dry wrinkles: common in wrinkled plum belly syndrome, dry skin wrinkles, named after plum-like wrinkles. Refers to the patient's partial or total abdominal muscles with severe hypoplasia or complete absence. The abdominal wall is composed of superficial fascia and peritoneum of the skin, without inguinal canal and ligament, and may be accompanied by giant renal cyst, giant ureter, renal hypoplasia, cryptorchidism. Wait. Because of the three major symptoms of abdominal muscle deficiency, urinary tract malformation and cryptorchidism, it is also called "triple syndrome".

Radioactive sulcus appears throughout the mouth: a symptom of the clinical manifestations of systemic sclerosis. Systemic sclerosis (scleroderma) is a connective tissue disease characterized by the hardening of collagen fibers in various skin systems. Systemic scleroderma involving the internal organs is also known as systemic sclerosis. The disease ranks second only to lupus erythematosus in connective tissue disease. The number of patients is more women, and the ratio of women to men is about 3:1. The age of onset is more common in 20 to 50 years old.
