Sunken scar

Introduction Depressed scars are defects in the dermis and subcutaneous tissue of the skin that can cause depressed scars, often caused by hemorrhoids, trauma, and chickenpox. According to the shape of the scar, there are several types such as linear scars, wart scars, concave scars, and bridge scars. For the most common sites of scar hyperplasia and keloids, such as the chest, shoulders, etc., there are tension and movement parts, such as the upper chest, the scapula, the flexion of the limbs, etc., where there is breast gravity and chest breathing. Such as the sternum, etc., postoperative scars are prone to hyperplasia, small lesions in these areas, such as cysts, fistulas and other surgical resection should be extra cautious.

Cause

Acne, surgery, trauma, infection, chickenpox and smallpox are common causes of depressed scars. These causes defects in the dermis and subcutaneous tissues of the skin. In the subsequent healing process, collagen and elastin are missing. Depressed scars.

Skin lesion

It is a superficial wound of the skin, which only affects the skin, starts from the epithelial cells of the hair follicles and sebaceous glands, and heals by simple epithelial formation. Complete restoration of structural integrity and skin function can be achieved after repair. The other type is damage deep into the dermis and subcutaneous tissue, which is repaired by scars. You should go to the dermatological examination of a regular hospital to determine the cause.

Differential diagnosis

Differential diagnosis:

(a) superficial scars

Superficial scars are caused by mild abrasion of the skin, or by shallow second degree burns, or by superficial infection of the skin, usually involving the epidermis or dermis.

(two) hypertrophic scars

Where the injury involves the deep layer of the dermis, such as deep II degree burns, cut wounds, infection, and the donor site after cutting the medium-thickness skin, may form hypertrophic scar.

(3) Atrophic scars

Atrophic scar, which affects the entire layer of skin and subcutaneous fat tissue, can occur after a large area of III degree burn, long-term chronic ulcer healing, and less parts of the subcutaneous tissue such as the scalp, anterior region, etc. Rear.

(iv) keloid

The occurrence of keloids has significant individual differences. Most keloids usually occur after 1 year of local injury, including surgery, lacerations, tattoos, burns, injections, animal bites, vaccinations, acne and foreign body reactions, and the history of many patients may be forgotten.
