What is it ( Nevus )?
Nevus ; They are usually benign brown, oval or round formations that can be seen all over the body. It refers to cells called melanocytes, which produce the pigment that gives skin its color, which will occur in the patient are likely in a genetically determined state. If some moles are present from birth, some of them appear especially during the growth period. But in genetically predisposed patients, new moles may appear throughout their lives. As moles mature, they divide into several forms:
- Mongolian spot: It is seen on the hips in newborns and disappears in childhood.
- Dysplastic nevi : These are benign nevi , but which histologically present atypical changes as in malignant melanoma.
- Spitz nevus : It is usually seen in children and on the face.
- Blue nevi : these are moles in which the melanin pigment is visible deeper in the skin.
- Congenital nevi : These are moles that are already present at birth and have already had a production of melanin pigment. They can reach gigantic sizes. They can be glabrous or hairy. 2-42% of these moles turn into skin cancer called malignant melanoma.
- nevus Junctional : They are usually seen in childhood.
- Compound nevi : They are generally observed during the transition to puberty.
- Intradermal nevus : these are raised moles seen in adulthood.
- Spider nevus : spider-like shape, often seen in children and women, usually bright red in color on the neck, face and upper chest. It occurs with sun exposure, estrogen therapy , and liver disease.
- Nevus of Ota and Nevus of Ito : Congenital flat brown moles on the shoulder or face.
Moles are benign skin lesions. They are not cancer cells. But some moles can turn into skin cancer over time. While 70% of skin cancers called malignant melanomas arise from normal skin, 30% are caused by a change in a pre-existing mole. Some skin lesions that people think of as “nevus” may actually be skin cancer. These must be surgically removed and treated.
With the follow-up and the recommendation of the medical specialist, it may be necessary to remove certain moles and examine them pathologically because they look like skin cancer or present a risk of transformation. On the contrary, not removing these moles and mole-like lesions and examining them pathologically can be life-threatening. Existing skin cancer may go unnoticed. Apart from this, the removal of moles by the person due to aesthetic or other concerns. it depends on your own will. Since it is perceived as bad among people, it has no carcinogenic effect, no increase in moles and no effect. On the contrary, it reduces the risk because cells that may pose a potential risk in the future are removed.
What are the surgical treatments?
The main treatment for me, benign skin lesions and skin cancers; This is an excision surgery. In this way, the lesion is removed and the removed part is examined histopathologically for precautionary purposes and if there is any unknown skin cancer, it is diagnosed early.
What is a lipoma (fat gland)?
The sebaceous gland is the tumorization of fatty cells under the skin in the form of a soft and painless nodule. Usually between 1 and 10 centimeters Although they have sizes, those who wait a long time can reach larger sizes. The outer parts of these structures, which can form in any region where there are normal fat cells, have a fibrous capsule. Caution should be exercised as their presence in more than one may indicate certain syndromic disorders.
Sebaceous glands are soft formations that move when stepped on. The sebaceous glands, which continue to grow for months and years, usually reach a size of 2 to 3 centimeters. In some people, the sebaceous glands of the skin, which can reach 10 centimeters, are expressed in the form of giant lipomas, in cases when they reach even larger sizes.
The reason for the formation of sebaceous glands in the body has not been fully diagnosed, but certain genetic events can progress to the formation of multiple sebaceous glands, and the presence of a family history of lipoma formation in these people is a factor. additional risk.
cosmetic concern
In sebaceous gland surgery, the doctor makes a small incision in the skin and aims to remove the sebaceous gland from this opening by squeezing it from below. Compression of the sebaceous glands is usually done under local anesthesia, and people can usually be discharged the day of the procedure. Larger incisions may be needed in large sebaceous glands. In some types of lipomas, vacuum tools, defined as liposuction, are used to clean out the formation.
For the treatment of sebaceous glands with liposuction, a thin tube is inserted through the opening in the skin in the first step. Then, with this tube, the absorption of fatty substances can be achieved and the sebaceous gland can be removed from the body. Tissue removed after sebaceous gland surgery is usually sent to the laboratory for examination under a microscope. In addition to these applications, injecting steroids into the affected area as a solution for sebaceous glands can shrink these structures.
