What are the symptoms of skin cysts

No matter what age we are, no matter whether we are male or female, we may suffer from skin cysts. The so-called skin cysts are actually what we commonly call cysts. In general, skin cysts are more likely to occur on the head and limbs of the body. There are many reasons for this disease, so in daily life we ​​must keep the facial skin clean and fresh, do not let the sebaceous glands of the skin be blocked, and do not scratch it hard when the face becomes itchy, to avoid damage to the facial skin or any possibility of facial skin infection. Now let’s talk about the symptoms of skin cysts.

Symptom 1.

Epidermal cyst: It is a cyst containing keratin in the dermis. It is caused by the epidermis being implanted under the skin due to trauma. The cyst wall is an epithelial structure, but the basal cell layer is the outer layer of the cyst wall. The stratum corneum is the inner layer of the cyst wall and is filled with keratin in the cavity. This disease often occurs on the scalp, neck, buttocks and back. Single or multiple, with diameters ranging from several millimeters to several centimeters, slowly enlarging, soft or hard in texture with a cystic feel, a movable base, and often adhesion to the skin. There are no small openings like sebaceous cysts on the skin surface, and there is no pain. Only when it occurs in the pressure-bearing area will there be compressive pain. It may be accompanied by secondary infection, and according to records, there is a possibility of malignant transformation.

Symptom 2:

Dermoid cyst: It is often a congenital lesion that occurs due to epithelial remnants from the embryonic period. It is a hamartoma and is composed of skin cells that have deviated from their original position. In addition to the epidermal cells of the cyst wall, it also contains sweat glands, hair follicles and sebaceous glands. The cavity contains desquamated epithelial cells, sebum and other porridge-like substances and hair.

Most of them are localized cystic tumors, which are discovered in childhood and adolescence. They grow slowly and are small in size. They are soft, round or hard cystic masses. It is located under the skin, has no adhesion to the skin, but is very tightly adhered to the basal tissue and is not easy to push. It is common around the eye sockets, root of the nose, occipital area and floor of the mouth, followed by the limbs. It can also occur on the chest and back. Long-term growth may lead to cancer.

Symptom 3.

Psoralea is formed by sebum accumulation caused by occlusion or stenosis of the sebaceous gland duct. The cavity wall is composed of epithelial cells without keratinization, and the outside of the capsule is fibrous connective tissue. It is filled with sebum, which gradually breaks down into a semi-fluid substance containing a large amount of cholesterol crystals.

Symptom 4.

Sebaceous cysts protrude from the surface of the skin, and patients generally have no symptoms. The tumor is spherical, single or multiple, medium hard, elastic, higher than the skin surface, adhered to the skin, not easy to move, smooth surface, without fluctuations, the center may be light blue, sometimes with openings on the skin surface, squeezing may reveal tofu dregs or noodle mud-like contents. If infection occurs, inflammatory reactions such as redness, swelling, heat, and pain may occur.
