What causes skin cysts?

Skin cysts are subcutaneous cysts that can occur at any age. They are mainly concentrated in the head, face, arms, back, etc. There are no obvious symptoms, and infection and suppuration may occur. Skin cysts are difficult to treat and may even require surgery and laser removal. Understanding the cause will help better prevent them. So, what causes skin cysts? Let’s take a look below.

When the sebaceous gland duct is blocked, cysts are formed due to the accumulation of sebaceous glands in the gland. Histopathological examination showed that the sebaceous glands underwent cystic changes. The cysts were filled with white powdery sebaceous gland secretions, broken sebaceous gland cells, and a large amount of cholesterol crystals with a foul odor. The outer layer of the cyst wall is composed of fibrous connective tissue, and the inner layer is composed of epithelial cells. When the cyst ruptures, foreign body giant cells may appear around it. People with sebaceous cysts should pay special attention to skin care, pay attention to hygiene, and take frequent baths, change clothes, and cut nails. Sebaceous cysts often occur in areas rich in sebaceous glands such as the head and face, and are prone to infection, causing local redness, swelling, tenderness, and even suppuration and rupture. Therefore, surgical excision is recommended, and the cyst wall must be completely removed during the operation, otherwise it is likely to recur.

It is not that it cannot be removed by taking medicine, nor will it go away on its own.

1. Surgery or laser removal. Western medicine surgery or laser surgery removal. If there are symptoms of inflammation such as redness, swelling, heat and pain before surgery, the inflammation should be controlled first and surgery should be arranged later. The disadvantage is that it is easy to leave scars and relapse. The entire operation process of the surgery is: during the operation, a fusiform skin incision can be designed along the skin grain direction on the skin connected to the cyst, especially when the duct opening is seen, and the cyst is removed together with the cyst. Be particularly careful during separation as the cyst wall is very thin and should be removed as completely as possible. Because it is under the skin, the operation is very difficult. If the cyst wall remains, it is easy to relapse.

2. Take anti-inflammatory drugs for 1 week after surgery. For oral administration of VC, B1, B2, etc., the dosage can be increased appropriately. The patient will recover within 7 to 10 days after the operation.

3. Check the wound dressing after surgery and perform local treatment if any signs of infection are found.
