Sebaceous cyst, commonly known as "pinoma", refers to the accumulation of sebaceous glands in the gland to form a cyst after the sebaceous gland duct is blocked. This is the most common benign skin tumor. Many people have experienced acne, especially young people who are in the period of vigorous growth and development.
Sebaceous cysts commonly occur on the scalp and face, followed by the trunk. Because they are of different shades and have different contents, their sizes vary greatly, ranging from the size of a grain of rice to the size of an egg. Often diagnosed as lipoma, fibroma, etc. Sebaceous cysts grow very slowly, but patients can still feel them getting bigger.
Sebaceous gland cysts are mostly single, occasionally multiple, round in shape, medium or elastic in hardness, higher than the skin surface, and have a smooth surface. When pushed, they feel connected to the surface but have no adhesion to the base. A sense of fluctuation. The skin color may be normal or light blue. When the growth rate is too rapid, the surface skin may be shiny. Sometimes there are openings on the surface of the skin, from which white tofu-like contents can be squeezed out. This opening is the opening that leads to the sebaceous glands on the surface of the skin. The depression in the opening is caused by the insufficient length of the duct. Sebaceous cysts are often complicated by infection, causing the cyst to rupture and temporarily disappear, but it will form scars and be prone to recurrence. The chance of a sebaceous cyst becoming cancerous is extremely rare.
Surgery is the only treatment for sebaceous cysts. During the operation, a fusiform skin incision can be designed along the direction of the skin lines in the skin connected to the cyst, especially when the duct opening is visible, and the cyst can be removed together. Special care should be taken during separation. The cyst wall is very thin and should be removed as completely as possible. If the cyst wall remains, it is prone to recurrence. If there are inflammatory symptoms such as redness, swelling, heat, and pain before surgery, the inflammation should be controlled first and surgery can be arranged later.
Treatment principles
1. Surgical resection: Once diagnosed, the cyst should be completely removed surgically.
2. Patients with concurrent infections should be given anti-inflammatory treatment such as oral antibacterial drugs (such as synergistic sulfonate tablets, medinomycin, etc.) and hot compresses, and surgical resection after the inflammation subsides.
You must listen to the doctor. If you need surgery now, it must be done. Don’t worry. The doctor has the dosage of anesthesia. If the scar is large, you can have plastic surgery.
