Melanocytic nevi or the well-known "moles" are benign tumours formed by clusters of cells called spilocytes.
The nevi are divided into: a).relatives, are evident from birth and in b). acquired, appear later.
How do we control nevus?
The initial screening of nevi is done by careful clinical examination combined with dermoscopy. The latter is a special clinical method in which a dermoscope is used, i.e. a special high-resolution and high-definition lens that allows dermatologists to see "inside" the lesion. In this way, in the first instance, moles are assessed and conclusions are drawn as to whether a mole should be surgically removed.
Some people with many nevi need to have digital nevus mapping. Digital nevus mapping uses very high resolution lenses to capture even the most subtle features of nevi. This method allows digital photography of areas of the body in order to be able to record and assess any new nevi that may appear, and also allows each nevus to be recorded individually.
How do we remove moles?
The ways of removing the nevus are the following:
- Laser removal: It is chosen as a method of resection only in the case where there is absolute certainty of benignity. The lesion is removed more superficially and usually the operation does not leave a scar.
- Shave-excision (removal of the mole by tangent): Removal is performed under local anaesthesia (xylocaine solution). After anaesthetising the area, the protruding nevus is removed with a blade. In case of additional removal and haemostasis, a CO2 laser or diathermy is used.
- Surgical resection: Moles that are suspected of being malignant or flat moles are removed by surgical excision with borders around them (healthy borders) so that they can be completely excised and sent for biopsy. In the case of surgical excision, there may be a scar (scar) depending on the depth of the mole, its size, where it is located and the healing capacity of each organism, which as can be improved in a second year with Laser.
