Melanocytic nevi and dermatoscopy

nevii melanocitari alunite - skinmed clinic

Melanocytic nevi, moles, are benign melanocytic lesions, often present in increased numbers in some, associated with a genetic predisposition.

There is a predisposition to develop melanoma from these benign lesions, and we currently know that 20% of malignant melanomas have pre-existing benign lesions.

And the risk of developing this malignancy is increased if the patient has more than 100 melanocytic lesions, which increases the risk of 7 or more than 50 dysplasia, increasing the risk by 6.4 times. 

Surgical prophylactic excision is not a solution because the diagnosis rate of a melanoma is 1 / 200,000 excisions, that is extremely low, and for this reason the idea of prophylactic excision is completely removed.

The correct attitude to excision is to treat surgically only malignant lesions; suspected lesions are monitored for a short term, because activity changes are rapidly observable when the lesion is a melanoma and its increase is extremely slow and maintained within safe limits.

Full body image monitoring and punctual dermatoscopic recording for some of the injuries are the right attitude. 

Prevention works, and early diagnosis is now possible with devices such as a FOTOFINDER that builds a full-body photographic map with automated take-up in standard positions to allow for accurate overlapping, with the device recording the changes between the two scans.

Dermatoscopic images for the lesions to be traced will also be taken, they will detect the microscopic changes.

Protecting pre-existing injuries  means, in fact, accountability.

The skin should not be overexposed in the sun or suffer sunburn. But it is more important to closely monitor these personal, subjective lesions by inspecting the entire skin surface of new lesions or noting alterations to pre-existing lesions, changes in shape, size, contour, surface, color. 

Any new lesion or alteration of a pre-existing lesion requires a dermatologist specialist who has to dermatoscopically analyze the lesion for an exact diagnosis or for establishing a course of treatment.
