Symptom
Once a wound appears on the skin, the body begins to heal automatically. There are two mechanisms for wound healing. If the wound is in the epidermis, the human body will create the same cell tissue to fill it without leaving scars. However, if the wound goes deep into the dermis, the skin creates strong scar tissue to effectively bind the wound in order to prevent the wound from cracking. Within three to six months after the injury, the scar tissue will continue to proliferate, known as the proliferative period. During this period, the human body will grow small blood vessels near the wound to provide nutrition for the scar tissue. Therefore, the early scars look red and convex, and feel like a rope. If the healing process is smooth, the proliferative period will enter the mature stage, and the scars in the mature stage will become light, flat and soft, with an average time of three to six months. But whether it is in the proliferative or mature stage, scar tissue will be constantly renewed due to the environment. It is not only a mass of meat on the wound, but also a living and changing tissue.
Classifications
Keloids can be generally divided into two types: original and follow-up.
The original type of keloids often occurs on the chest or shoulder, with small red spots and itching at the beginning, gradually from small to large, from soft to hard. The color is red or dark red. There are cable-like, butterfly-like, round, irregular shape and so on.
Follow-up keloids are also called hypertrophic keloids. They often cause excessive proliferation of damaged tissues, destruction and degeneration of subcutaneous tissues due to burns, scalds, trauma, acne, infection and suppuration and so on. They protrude from the skin. The color is red or dark red with itching or tingling. Some of them have capillaries that extend significantly outwards. Symptoms tend to worsen after drinking alcohol or eating irritant foods such as spicy foods and so on.
Features
Frequently occurring parts: common in the chest, shoulder, auricle, jaw, upper back.
The lesion is long and lasts for many years. As the lesion progresses, the scars gradually extends to the surrounding normal skin beyond the original base.
It is very easy to relapse after simply performing surgical resection and suture treatment. Moreover, the stronger the hyperplasia, the larger the scar area and the faster the growth rate. Therefore, surgical resection cannot be performed at will.
