Stretch marks

Introduction to shrinking lines The atrophic pattern, also known as the invasive pattern, the white line, occurs in the pregnancy period called the stretch mark, the dermis elastic fiber is broken and the skin is over-extended and the atrophy changes. Occurs in the knees, elbows, underarms, groin, inner thighs, buttocks, abdomen, breasts, etc., more common in puberty, pregnancy, lactation, body growth is too fast, Cushing and long-term application of corticosteroids. basic knowledge The proportion of illness: 0.003% Susceptible people: no special people Mode of infection: non-infectious Complications: obesity

Atrophic disease

Endocrine factors (55%):

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

Other factors (45%):

Due to the abundance of nutrients in the body, it leads to obesity or skin overextension caused by excessive abdominal abdomen during pregnancy, and this symptom is caused by the breakage of elastic fibers.

Pathogenesis

The dermis elastic fiber is broken and denatured, and the skin is over-extended and the atrophy changes.

Shrink prevention

There is no effective preventive measure for this disease. Early detection and early diagnosis are the key to the prevention and treatment of this disease.

Atrophic complication Complications obesity

The disease is a benign disease of the skin. Due to endocrine changes, the adrenal gland has short corticosteroids, which increases the decomposition of elastic fibrin, denatures collagen fibers and elastic fibers, and inhibits fibroblast function, resulting in skin elasticity due to increased skin elasticity. Stretch, the elastic fiber breaks and causes the disease. No serious complications. Long-term use of glucocorticoids can reduce local immunity and cause skin infections.

Symptoms of wrinkle lines Common symptoms Eye wrinkles Skin pattern Swelling atrophic pattern Abdominal skin appears white...

The skin damage is reddish or purple-red at the beginning, and the micro-longed skin changes in the shape of the skin. The boundary is clear and arranged along a certain grain direction. Afterwards, the damage gradually changes to pale white, micro-depression, soft and atrophy, and there may be fine wrinkles. The epidermis can be seen with microvessels, which are difficult to regress in the long term. There are no symptoms. It occurs in the knees, elbows, underarms, groin, inner thighs, buttocks, abdomen, breasts, etc. It is more common in puberty, pregnancy, breastfeeding, and the body grows too fast. Cushing has a long-term application of corticosteroids.

Examination of shrinking lines

Histopathology: epidermis, dermis thinning and atrophy, collagen fibers are separated from each other, and the central elastic fibers disappear, and the edges are curled and clumped. The old damage can be seen by regenerating straight collagen fibers and slender elastic fibers. No elastic fiber residue.

Diagnostic identification of atrophic lines

According to the clinical manifestations, the characteristics of skin lesions and histopathological features can be diagnosed.

Histopathology: epidermis, dermis thinning and atrophy, collagen fibers are separated from each other, and the elastic fibers in the center disappeared, and the edges were curled and clumped. Old damage can be seen by regenerating straighter collagen fibers and fine elastic fibers. There is no elastic fiber residue below this area.
