How can you tell if it s a sebaceous cyst?

Sebaceous cyst, also known as "pink tumor", is a kind of cyst formed by the blockage of the sebaceous duct and the accumulation of sebum without excretion. This cyst is one of the most common lumps on the body and is more likely to occur on the face, back and buttocks. Taller**, spherical, about the size of soybeans to grapes, soft texture, and sacs**.

In the case of concurrent infection, there is an inflammatory reaction on the surface of the cyst and the surrounding tissues, which is red, swollen, painful, and oops, and after the ulceration, something like tofu comes out.

Sebaceous cysts can be surgically removed, and if the resection is not complete, it can be caused by residual cyst wall**.

Sebaceous cysts, commonly known as "pink tumors", refer to the formation of cysts in the glands due to the accumulation of sebaceous glands after the ducts of the sebaceous glands are blocked. This is one of the most common benign tumors, and many people have experienced powdery tumors, especially young people in the vigorous growth and development period.

Sebaceous cysts tend to occur on the scalp and face, followed by the trunk. Due to its different shades and contents, its volume and size are unequal and the difference is large, the small ones are the size of a grain of rice, and the large ones are the size of eggs. Often diagnosed as lipomas, fibroids, etc.

The sebaceous cyst grows very slowly, but the patient can still feel it gradually enlarge.

Sebaceous cysts are mostly single, occasionally multiple, round in shape, medium or elastic in hardness, high above the skin surface, smooth surface, and feel connected to the surface when pushed but no adhesion to the base, no fluctuation. The color may be normal, or it may be light blue, and when it increases too quickly, the surface can be bright. Sometimes there is an opening on the surface of **, from which the white tofu dregs-like contents can be squeezed out.

This opening is the opening leading to the sebaceous glands on the surface of **, and the depression of the opening is caused by the insufficient length of the duct. Sebaceous cysts tend to be complicated by infection, causing the cyst to rupture and regress temporarily, but they can form scarring and are prone to **. The chance of a sebaceous cyst becoming cancerous is extremely rare.

Surgery is the only way to treat a sebaceous cyst. During the operation, a fusiform incision can be made along the direction of the stria and removed together with the cyst at the ** connected to the cyst, especially when the catheter opening is seen. Special care should be taken during separation, as the walls of the cyst are thin and should be removed as intact as possible.

If the cyst wall remains, it is easy to **. If there are inflammatory manifestations such as redness, swelling, heat and pain before surgery, the inflammation should be controlled first, and surgery should be scheduled later.

**Principle 1 Surgical excision: Once the diagnosis is confirmed, the cyst should be surgically removed completely.

2 Patients with complicated infections should be given oral antibacterial drugs (such as synergistic bisulfon tablets, medisomycin, etc.) and anti-inflammatory** such as hot compresses, and surgical resection after the inflammation subsides.

If you want to follow the doctor, if you want to do the surgery now, you must do it, don't worry, the doctor has a dose of anesthetic, and you can have plastic surgery if the scar is large.

Patients with sebaceous gland Ransenling cyst should have the following basic examinations before undergoing hand skin surgery**

1. Know the medical history. During the examination, the doctor will ask about the time, location and development of the sebaceous cyst, so the patient should pay attention to the time of onset and the development of the cyst after the onset of the disease.

2. Understand the condition of cysts. Sebaceous cysts are generally single or multiple, as soft or slightly firm spherical masses, their diameter is generally 1 3cm, these sebaceous cysts are generally located in ** or subcutaneous tissue, will adhere to **, but their base can be moved, sometimes you can see on the surface of the cyst sebaceous gland opening blocked caused by the appearance of small black spots of spring branches.

3. Puncture examination. In addition to diagnosing a sebaceous cyst based on the history and clinical presentation, patients usually undergo a puncture in which the doctor can remove milky okara-like discharge from the sebaceous cyst, sometimes with hair visible on the gross specimen. Structures such as exfoliated epithelial cells, hair follicles, and sebaceous glands can be seen under the microscope, which can help doctors understand the development of sebaceous cysts in more detail.

1. Spherical mass. Cortical cysts typically appear as soft or slightly firmer spherical masses on the sebaceous gland-rich face, which can be as small as a bean or as large as a small citrus. These cysts are generally round, located in the skin, and protrude to the surface, and the cyst wall is tightly adhered to, and it can have a small pigment point, which can squeeze out the gray-white curd-like, foul-smelling contents from the opening, which will be like white tofu residue.

2. Secondary infection. Sebaceous cysts can be secondary to infection, which can be manifested as: local redness, swelling, softness, increased skin temperature, pain, and suppuration.

3. The sebaceous cyst occurs slowly, is round, has an obvious boundary with the surrounding tissues, has a soft texture, is non-tender, and can be moved. There are usually no symptoms.

It should be distinguished from dermoid cysts, epidermoid cysts, and subcutaneous lipomas.

1.Dermoid cysts.

It is a congenital cyst formed by the deviation of the original cell primordium of ** cells, located under the skin, not adhesion to ** but very tight adhesion to the basal tissue, often near the midline of the body, and is likely to occur around the orbit, root of the nose, occipital region and floor of the mouth, etc., which is a hamartoma.

2.Epidermoid cysts.

Also known as traumatic epidermal cyst. It is a kind of cyst containing keratin in the dermis, which is mostly caused by trauma (especially puncture wounds) implanted into the dermis, and the surface of the lump often has keratin hyperplasia, which tends to occur in the hands and ankles and other parts that are susceptible to trauma and compression.

3.Subcutaneous lipoma.

The lipoma is flattened and lobulated, located under the skin, and is pushed locally along both sides of the tumor with the fingers**, and the orange peel sign may appear.
