A nevus should be removed if it is suspected to change into malignancy or because it is in a location that is frequently injured and causes problems in everyday life, or because it causes aesthetic problems for the patient. The appropriate way of removing a nevus should be decided after discussion with the dermatologist. In general, the ways of removing moles are as follows:
The laser method of removing a mole is only suitable if it is absolutely certain that it is a benign lesion (nevus without risk of outbreeding, papillomas, papules, seborrhoeic warts, etc.). The method of removing a mole by laser is only suitable if it is absolutely certain that it is a benign lesion (nevus without risk of outbreeding, papillomas, papules, seborrhoeic warts, etc.). We always aim to removing a lesion without causing scars.
A simple and quick way of removing a mole, where the protruding part of the mole is cut with a blade under xylocaine local anesthesia. Hemostasis and additional removal of any residual part can be achieved by CO2 laser or diathermy.
When the nevus is flat or when malignancy is suspected, preventive surgical excision of the nevus as well as the borders around it by a Plastic Surgeon is recommended so that the fragment can be sent for biopsy.
The scar that will remain after the removal of the nevus depends on its size, the way it was removed and the healing capacity of the body.
Nevi - skin moles - are extremely common, and there is no adult human being without a mole on their skin. Some people even develop them in quite large numbers.
Individuals with moles should consult their dermatologist. Many seek their removal for both aesthetic and medical reasons.
Monitoring them is of great importance as they are sometimes the substrate on which malignant melanoma, the most aggressive malignant skin tumor, develops.
Melanocytes in nevi become cancerous mainly due to the effect of solar radiation which causes mutations and damage to the DNA of the cells resulting in uncontrolled proliferation.
A less common, but extremely aggressive type of skin cancer is melanoma. Melanoma is caused by melanin cells, the cells that produce melanin, the pigment that gives the skin its characteristic color. In advanced stages, melanoma can cause metastases and can even be fatal.
The person should be informed and consult a dermatologist, in case a new nevus (mole) with an irregular shape appears or in case he/she notices that an existing nevus has altered (based on the aforementioned criteria). Characteristics of the alteration can be a change in size, shape or colour, as well as ulceration or bleeding of the mole. The most common sites of occurrence are mainly the back, arms, legs or face, as well as the genitals. In men it occurs mainly on the trunk, while in women it occurs on the lower limbs.
Moles on the face are very common, as due to sun exposure the head is the most common location of moles. Facial nevi can be congenital (usually hair bearing) or acquired. Facial nevus may be congenital, mixed, choroidal, sebaceous, vascular, Comedo, Spitz's nevus or OTA nevus.
In facial nevus one should notice if there has been a change in shape, color, size and visit the Dermatologist for immediate examination and diagnosis.
Facial nevi can often be confused with seborrheic hyperkeratosis, radial hyperkeratosis, smooth warts, hemangiomas, xanthelasma, senile spots or freckles.
The correct diagnosis of a mole on the face will only be made by a dermatologist after a dermatoscopy and clinical examination, who will recommend the best treatment.
Facial moles often cause aesthetic problems and many patients resort to their removal mainly for aesthetic and self-confidence reasons.
However, facial moles may conceal malignancy and lead to malignant melanoma or may be a more innocent form of skin cancer such as basal cell carcinoma.
In any case of removal of a facial nevus, it should be sent for biopsy in order to get a response at the microscopic level from the pathologist.
Nevi on the genitals are rarer than nevi on other areas of the body. Special care should be taken when a mole appears on the genitals, as this area is not exposed to the sun and the appearance of a mole may conceal another more serious disease.
Genital nevi may be congenital, conjunctival, chorionic, mixed, vascular or sebaceous. In some cases, lesions such as genital warts, papillomas, angiokeratoma, bowenoid papulosis, or even a genital squamous cell carcinoma are mistakenly taken for genital nevi.
Rare but real, there is a risk that a genital nevus may hide a melanoma of the skin or genital mucosa, which is a very aggressive form of malignancy.
In any case of the appearance of a new genital nevus or a change in a pre-existing genital nevus, it should be surgically removed and biopsied in order for the dermatologist to make the correct diagnosis.
In case the genital nevus is proven to be of HPV etiology, the solution is the CO2 laser, while in case it is proven to be a carcinoma or melanoma, a wider surgical excision is necessary for proper treatment.
It is a common belief that removing a mole from our skin can lead to cancer, which is completely false.
There is never a chance that removing a mole will cause skin cancer or melanoma. On the contrary, not removing a suspected mole can lead to its outbreak and turning it into cancer.
Therefore, when a skin mole is suspicious and the dermatologist suggests removal and biopsy, this should not be neglected and should be done as soon as possible.
