Dermatoscopy is the examination of the skin with the help of a dermatoscope. It is a non-invasive, diagnostic technique that magnifies skin lesions to such an extent that the diversity in their color becomes visible, the internal architecture and morphological characteristics of the fault, items not visible to the naked eye or with the normal magnification of common magnifying glasses.

With the appropriate training and experience, Dermatoscopy improves the diagnosis of pigmented and non-pigmented, benign and malignant skin lesions, with the main benefit of its contribution to the early diagnosis of melanoma.

In addition to the widespread impact of dermatoscopy on the examination of nevi (olives of the skin), its use extends to other skin diseases such as hemangiomas, seborrheic and radial hyperkeratosis, skin epithelium (basal cell, squamous cells).

It is important to know how a "suspicious" nevus is evaluated:

Nevi are roughly evaluated based on the ABCD algorithm, where

A corresponds to asymmetry (asymmetry, one half is not similar to the other half)

B corresponds to the border (abnormally, or vaguely outlined boundaries of the lesion)

C corresponds to color (variety that includes shades of brown, black, white, red or cyan)

D corresponds to the diameter (diameter greater than 6 millimeters or increasing in size nevus).

The patient's self-examination is considered very important. If a patient notices changes in a nevus, should visit his Dermatologist for examination. Notable changes in a nevus are considered:

-Sudden bleeding (without the patient remembering an injury)

-Change in the aesthetics of the nevus (stings, itching-itching)

-Changes in color and mainly the appearance of color variety in the same lesion.

-Changes in the shape mainly appearance of pseudopods (protrusions, feet) in the periphery of the lesion

-Changes in the nevus and / or surrounding area of ​​the skin: erythema (blush), edema (swelling), ulcer (wound that does not close)

Finally, people with a burdensome family history (melanoma) or numerous nevi, or great relatives (present from birth) nevi should be examined prophylactically by a dermatologist at least once a year. In these patients it makes sense to save the dermatoscopic images for comparison in a later test, a process called mapping.

"Dermatoscopy is a weapon that dermatologists have had for the last decade to very effectively examine the shape and internal structure of an olive tree., a nevus. With dermatoscopy we see the olive inside, we see its internal symmetry, we see its internal shapes so if we see something worrying we put the patient in a regular monitoring, in a mapping that depicts all the olives on the body or we suggest the surgical removal of the suspicious olive. This way we can deal very effectively with a potentially suspicious lesion and prevent it from evolving., its mutation into a skin cancer which is something very serious. The process is easy, is completely painless for the patient, it does not last long and offers us very important security. "
