Reasons for the appearance of new red moles on the body
A nevus is a visible limited chronic lesion of the skin or mucous membrane. Nevi are congenital and acquired (most often appear in childhood and adolescence). The term "nevus" is used to denote conditions caused by neoplasia and hyperplasia of melanocytes, as well as a number of pigmentation disorders. Nevi do not belong to the type of dangerous malignant moles. The probability that a single nevus will occur is extremely small. However, patients with a total number of benign moles of more than 50 are at increased risk of developing melanoma.
Types of nevi:
- melanocytic;
- papillomatous;
- dysplastic;
- intradermal (intradermal);
- blue;
- warty;
- comedonic;
- lentigous;
- hairy (Becker's nevus);
- juvenile (Nevus Spitz) and others.
Where can you remove a mole with a laser
Large nevi, as well as those located in places of possible trauma, such as bulging black moles on the neck, should preferably be removed. Such formations are rubbed with clothing, injured and, as a result, easily ignited. Constant mechanical impact can cause tissue degeneration (malignancy).
Choosing the method of removal is the doctor's prerogative. Which doctor should I see to check moles? It is better to consult a dermatologist-oncologist in a specialized clinic. In the case of deep nevi of large sizes, as well as in the case of the slightest suspicion of malignant tissue degeneration, surgical removal is indicated. During surgical excision, it is possible to conduct a histological examination of the tissues of the mole. The operation is performed under local anesthesia. A small scar is usually left after excision.
Modern methods - laser and radio wave removal. Scars do not remain after removal of moles on the face with the help of a laser, the laser minimally injures tissues. The wound heals within 5-7 days without leaving a scar. Only slight depigmentation of the skin is possible. Where can a mole be removed with a laser? - in specialized medical centers or clinics of aesthetic medicine, which have dermatologists on staff.
What to do if a mole grows and itches or hurts
Mostly moles appear in adolescence, during pregnancy, after stress. The reasons for the appearance of new red moles on the body are heredity, ultraviolet radiation, changes in the hormonal background. Vascular birthmarks are clusters of small blood vessels, they are benign neoplasms.
If brown moles appear on the back, it may be the so-called solar lentigo. The cause of formation is long-term exposure to ultraviolet radiation. Solar lentigo mostly occurs in fair-skinned people. Dark-skinned people have a higher content of the melanin pigment, which provides a certain degree of photoprotection, so the disease is rarely observed in them.
A flat white birthmark on the hand is a non-pigmented nevus that is formed as a result of a reduced content of melanocytes in the skin. In children, the appearance of such moles is usually associated with a failure in the process of moving melanoblasts during the fetal period, in adults it may indicate the dermatological disease vitiligo.
What to do if the mole grows and itches or hurts? If the nevus becomes painful, itches, bleeds, is covered with ulcers, you should immediately consult a doctor. In order to carry out microscopic diagnostics in order to detect the degeneration of moles, a special biopsy is performed, which allows to avoid extensive surgical removal of a benign formation.
Nevus in children
Nevi are laid during the fetal period, that is, before the birth of the child. And they can appear only after 2-3 years. A special form of a nevus is a formation on the mucous membrane of the eye. Congenital giant pigment nevus on the eye of a newborn child occurs in 2-5%. It is better to remove such formations surgically. The doctor decides when to perform the operation. If the child has a "calm" nevus that does not disturb or spoil the appearance, then it is better to postpone the operation until 9-10 years old, when the child will more easily tolerate anesthesia, post-operative manipulations and hospital stay. Before this age, only a doctor's observation is recommended. If the specialist notices signs of activation (change in color, vascular pattern, dispersion of pigment around), then the operation should not be postponed.
The doctor examines the nevus with the naked eye or using a dermatoscope. For the study of melanocytic nevi, more advanced imaging methods are available, such as computer dermatoscopy. The doctor decides on the need to remove the nevus, taking into account the type of formation and the degree of diagnostic uncertainty. Most nevi are benign and should only be observed, but some may require histopathological examination. Analysis will show whether the pigmented nevus is a type of melanocytic nevus, dysplastic nevus, or melanoma. Criteria for oncological surveillance regarding nevi in adults are asymmetry, blurring, visible changes, diameter greater than 6 mm. In addition to the histopathological examination, other tests may be required. As a rule, nevi that have existed since childhood are safe.
