Is the presence of dysplastic moles more risky for melanoma development?
The possibility of developing melanoma from an existing dysplastic mole is extremely rare. Expected feature, dysplastic
The mole, like other ordinary moles, remains the same and does not change in adulthood. However
In the presence of change, melanoma may develop. According to our knowledge, people with these moles
The risks of melanoma that can develop on normal skin are higher than those without dysplastic moles.
In other words, individuals with dysplastic moles can develop from normal skin rather than developing through moles.
The risk of melanoma is higher.
Should all dysplastic moles be surgically removed?
No. These moles are benign. Prevent unnecessary surgery costs and scars that may occur in patients
moles can be surgically removed only in cases where diagnosis is difficult or melanoma cannot be distinguished.

Should individuals with dysplastic moles be followed?
Yes. The purpose of following the people with dysplastic moles is to
to follow the changes that may develop and to detect the new melanoma early.

Are there any precautions that patients with dysplastic moles should follow?

but may appear in the first 2 years of life, which are called “late-onset congenital moles”.
How far do congenital moles go?
Congenital moles grow in proportion to the child’s body as it develops and grows. These moles
They are divided into 4 groups according to their final size (diameter) that they will reach at adult age.
“Little congenital mole” for those less than 1.5 cm
“medium size congenital mole” for those who are between 1.5-20 cm
Big congenital mole for those larger than 20 cm
Those larger than 40 cm are called “giant congenital moles”
How common are congenital moles?
Small congenital moles are approximately one in 100 births, large ones are approximately one in 20,000 births and giant ones
Congenital moles occur once in 500 000 births.
What is the appearance of congenital moles?
Small to medium-sized congenital moles are usually sharply circumscribed, smooth-surfaced, light or dark brown
It appears in the form of spots and sometimes as rough brown bumps. on them

Moles are usually located on a large part of the body such as the back and cover a large part of the skin.
Small and large ridges of brown and black color contain thick, stiff bristles.
A few or many smaller “satellites” (satellites) around large and giant congenital moles
so-called moles can be found.
Are congenital moles dangerous?
Originating from cells called melanocytes that give color to the skin, although rare, on congenital moles.
A mole cancer called “melanoma” can develop. The risk of developing melanoma is related to the size of the mole. Small

symptoms such as restlessness, headaches, recurrent vomiting and epileptic seizures are seen.
How should congenital moles be followed?
Follow-up of congenital moles differs from patient to patient. Benin’s location, size, cosmetic and
negative psychosocial effects should be taken into account. Small size and smooth surface,
congenital moles located in an easily traceable area of the body at regular intervals (such as 6 months-1 year)

Is surgical removal of congenital moles dangerous?
Contrary to popular belief, removing moles does not pose a danger, on the contrary, a mole with suspicion of cancer
Early removal with appropriate technique can save lives.
Can the risk of developing cancer on congenital moles be reduced?
Sunlight is an additional risk factor for the development of cancer. Therefore, both me and those outside the clothes
must protect the entire skin from sunlight. For this, unless it is necessary between 10:00-17:00
should not go out under the hot sun, and when you have to go out, you should be protected from the sun with a protection factor of at least 30.
Protective creams should be used, and bare skin should be covered with wide-brimmed hats and clothing.
