Symptoms of a powdery tumor, what causes a powdery tumor? How can it be prevented?

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. The clinical manifestations are as follows:

The cyst is a single or multiple, soft or slightly firm, spherical mass, 1 3 cm in diameter, located within ** or subcutaneous tissue, adherent to **, but the base can be moved. Sometimes small black spots are visible on the surface of the cyst due to obstruction of the opening of the sebaceous glands.

The cyst is of medium or elastic hardness, rises above the skin surface, has a smooth surface, and feels attached to the surface when pushed but does not adhere to the substrate, and there is no feeling of fluctuation. The color may be normal or light blue, and the surface may be shiny when it increases too quickly. 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.

First of all, it is clear whether it is a pink tumor, because it is very similar to epidermal cysts, dermoid cysts, and hypertrophic external hair root sheath cysts.

1 Powdery tumors, also known as sebaceous cysts, occur in areas where the sebaceous glands are densely distributed, such as the midline area of the head and back. The cause of the formation is the obstruction of the opening, and the sebaceous gland secretion cannot be excluded, which is a retained cyst. Surgery should be the mainstay**, and some mild ones can be opened to help the sebaceous glands to eliminate the symptoms, and anti-inflammatory after surgery with infection**.

Prevention: Wash frequently, especially after exercise; Do not squeeze, avoid, infection. If it is multiple, such as in a clustered distribution, it needs to be differentiated from multiple lipitic tumor.

2 Epidermal cyst: usually caused by the embedding of epidermal components after trauma, with keratinates inside, squamous epithelium on the cyst wall, and no sebaceous gland components, its components originate from the external orifice part of the external hair root sheath. Limbs and trauma sites are more common, and ** are also surgically removed.

3 Dermoid cysts: mostly found in the midline of the body, but also on the head, and are usually adherent to the surrounding tissues. Surgery is the main one, and the chances are high. Originates below the opening of the outer hair root sheath.

4 Proliferative external hair root sheath cyst: Rare, more common in women than men, and secondary tumors are more common. The cyst wall is an external hair root sheath cell, with basal layer-like structures and eosinophilic changes in the intracapsular epithelium. **Surgical resection is the mainstay, and the ** rate is high.

Pink tumors, medically known as sebaceous cysts. It is a "small tumor" formed by the accumulation of sebaceous secretions caused by the blockage of the opening of the sebaceous glandular duct and the gradual enlargement of the gland. Pink tumors tend to occur during puberty, especially on the face.

The powder tumor is located in the superficial layer, generally spherical, rice grains to the size of eggs, **blackheads are visible, and white powder is discharged when squeezed.

Facial powderomas grow slowly, can persist for many years without symptoms, often go unnoticed, and are often large or infected before going to the hospital. There are even people who have the wrong idea that "pink tumors don't need **".

Powdery tumors are potentially dangerous for long-term existence. First of all, the size of the powder tumor increases the difficulty of surgery, and the scar is longer, which affects the appearance. Secondly, the pink tumor is prone to redness, swelling and ulceration, which makes the wound not easy to heal. In addition, it has been reported in the literature that there is a possibility of carcinomy if it exists for a long time.

Therefore, everyone should pay attention to facial hygiene, often use facial cleanser to cleanse (especially those with oily**), and eat less greasy food. Once a pink tumor is found, you should seek medical attention as soon as possible and have early surgery.
