Introduction
Introduction The giant scar is also called crab foot swelling or keloid, which is a kind of fibroid and is a product of excessive proliferation of fibrous connective tissue. Hyperplasia of scars and scars is an important complication of trauma and trauma. There are many causes of keloids, such as burns, trauma, trauma, hemorrhoids (acne), ear piercing, and vaccination. Different degrees of scar hyperplasia and keloids are formed. Scars are often characterized by itching and pain during active hyperplasia. Some patients have worsened symptoms on rainy days, and some patients have intensified after eating spicy foods such as spicy.

Cause
Hyperplasia of scars and scars is an important complication of trauma and trauma. There are many causes of keloids, such as burns, trauma, trauma, hemorrhoids (acne), ear piercing, and vaccination. Different degrees of scar hyperplasia and keloids are formed. Its preventive measures are mainly in the stage of scar formation and immature formation. The main purpose is to remove all kinds of factors that cause scar hyperplasia, reduce the growth of scars, and prevent various deformities and dysfunction caused by scars on the body.

Self-diagnosis method of keloid:
Symptoms: Scars are often characterized by itching and pain during active hyperplasia. Some patients have worsened symptoms on rainy days, and some patients have intensified after eating spicy foods such as spicy.
Causes: In addition to secondary trauma and surgery, keloids are more common in vaccination, insect bites, hemorrhoids, and skin damage caused by unknown causes.
Partial examination of scars:
Scar morphology: can be strip, round, oval, or irregular.
Number of scars: one or more scar colors: can be divided into red, pink, red, purple, deep red and other types.
Scar texture: can be divided into soft, very soft, slightly hard, hard, hard, or blisters.
Scar thickness: It can be divided into thin, thin, slightly thick, thick, and obviously thickened.
Occurrence site: One or more parts can occur simultaneously.
Lesion range: Pay attention to whether the scar exceeds the original damage range. Changes in body temperature: large areas of hypertrophic scars can reduce the heat dissipation effect of the skin, affecting the body temperature regulation function, and the body temperature rises.
Malformation state: Check the loss of the body function caused by the deformity caused by the scar to the body. Complications: presence or absence of infection, ulcers, leaks and crypts.
Diagnosis
Differential diagnosis
Scar hyperplasia: Scar hyperplasia Scar hyperplasia, also known as keloid, is caused by excessive proliferation of fibrous connective tissue. The keloid ridge has a tumor-like hyperplasia, a smooth surface, a rosy and shiny color, and often found dilated capillaries. Skin damage extends outward from the edges and the crab feet deform. Skin lesions vary in size, shape difference, and hard, such as cartilage, and the symptoms are more itchy or painful or burning. Due to the acute pain, it may be caused by the conduction of nerve endings or the formation of microneuromas, even when the clothes are gently touched. The development is relatively slow, and most of them continue to increase. Some scars and surrounding tissues are bright and the color is slightly white. There is very little self-retraction, and occasionally there is malignant change. Keloids occur in the chest, shoulders, neck, back and auricle, and are rarely found in the eyelids, palms, ankles and external genitalia. The onset of the skin on the chest of women is the most common, in addition to the internal factors, may be related to the weight of both breasts and respiratory movements.
Scar formation: The formation of scars is caused by the body's inflammatory response, imbalance of collagen synthesis and degradation, the appearance of abnormal mucopolysaccharides, and the proliferation of fibroblasts. Reduced lymphatic drainage in hypertrophic scars, local edema, can lead to hypertrophy of scars, is an inevitable outcome of the body's wound repair.
Depressed scars: Defects in the dermis and subcutaneous tissue of the skin can cause depressed scars, often caused by hemorrhoids, trauma, and chickenpox.
