skin cyst
Introduction
Introduction to skin cysts It occurs at any age. It is common in the head, arms and back of youth. It is a soft or soft or solid ball with a diameter ranging from 1 to 3 cm. The powder tumor is buried in the skin or subcutaneous tissue, adheres to the skin, and the substrate can move. The open surface of the skin can be seen. When the cyst is pushed, the adhesion to the skin is very tight, and there is a slight depression and a small pit appears, which is the opening of the catheter where the gland directly reaches the surface of the skin. Some of the openings are filled with a black acne-like peg to extrude white waxy material. The disease has been asymptomatic for many years, easy to secondary infection, suppuration and ulceration, and some stinks are unpleasant. The literature reports cancerous changes, most of which are converted to basal cell carcinoma, and a few become squamous cell carcinoma, with a cancer rate of about 2.2% to 4%. . basic knowledge The proportion of illness: 0.025% Susceptible people: no special people Mode of infection: non-infectious Complications: lipoma basal cell tumor
Cause
Cause of skin cyst
Cause
Frequent in youth, often due to skin trauma, sometimes the incidence and trauma interval for many years or the injury is slightly difficult to recall.
Prevention
Skin cyst prevention
Special attention should be paid to skin care, to be hygienic, to take a bath, to change clothes, to cut nails, to squeeze the cysts, to avoid inflammation caused by human stimulation, and those with larger cysts can seek surgical removal, if there is secondary Infection, can be used as local moist heat, take antibiotics in time, and then remove cysts after the inflammation is eliminated or controlled. If the cyst is already purulent, you should go to the hospital for incision and drainage. After the wound is healed, the cyst can be removed. .
Avoid fried and spicy food, spicy food such as pepper, onion, raw garlic, pepper, etc., diet should pay attention to light, more food porridge, noodle soup and other foods that are easy to digest and absorb, eat more fresh fruits and Vegetables to ensure the intake of vitamins.
Complication
Skin cyst complications Complications lipoma basal cell tumor
Long-term growth can occur cancerous, and secondary infection, according to the record of malignant changes.
Symptom
Symptoms of skin cysts Common symptoms Cystic cystic mass secondary infection
(1) Epidermal cyst: It is a kind of keratin cyst in the dermis, which is formed by implanting the epidermis into the skin due to trauma. The cyst wall is epithelial structure, but the basal cell layer is the outer layer of the cyst wall, and the stratum corneum is the inner layer of the cyst wall. And filled with horny matter in the cavity, the disease occurs in the scalp, neck and hip, back, single or multiple hair, ranging from a few millimeters to several centimeters in diameter, slowly increasing, soft and hard, with a sexy capsule, the base can be Move, often adhere to the skin, the skin surface does not have open pores like sebaceous gland cysts, no pain, such as pressure pain occurs when the pressure is on the site, and secondary infection, according to the record of malignant possibility.
(2) Dermoid cyst: often congenital lesion, due to epithelial residual in the embryonic stage, is a hamartoma, due to the original skin cells deviating from the original, in addition to the epidermal cells of the wall, still containing sweat glands, hair follicles And sebaceous glands, etc., the cavity contains exfoliated epithelial cells, sebum and other atheroma and hair.
Most of them are localized cystic masses. They are found in young children and adolescents. They grow slowly and have a small volume. They are soft round or hard cystic masses. They are located under the skin and have no adhesion to the skin, but they are very tightly adhered to the basal tissue. It is not easy to push, it occurs around the eyelids, the nasal roots, the occipital and the bottom of the mouth, followed by the limbs, the chest and back also see the onset, and the long-term growth can cause cancer.
(3) The powder tumor is formed by sebaceous accumulation caused by occlusion or stenosis of the sebaceous gland cyst. The wall of the cavity is composed of epithelial cells, with no keratinization, and fibrous connective tissue outside the capsule. The sebum is gradually decomposed into semi-fluid. The substance contains a large amount of cholesterol crystals.
Examine
Examination of skin cysts
Pathological biopsy can confirm the diagnosis.
Diagnosis
Diagnosis and differentiation of skin cysts
Skin cysts should be differentiated from various types of tumors that occur on the surface of the skin. Some cases can be found only during surgery, especially under the skin. Because the tension is too large, some do not move, and it is easy to consider fibroids.
Should be differentiated from multiple lipid sac tumors, lipomas and neurofibroma, according to pathology can be diagnosed.
