Nevi (commonly olives) benign summations dermal origin cells with varying characteristics.
Although most people recognize as the warts arising from melanocytes (nevi Melanocytic) however there are many other categories. Melanocytic nevi are divided in congenital and acquired. Relatives exist from birth or appear soon after and divided into small, medium and large (diameter over 20 cm) the latter is relatively dangerous as there is a moderate probability of developing melanoma on them and should be removed from plastic surgeons. The acquired nevi appear progressively during life, with increased frequency after puberty, reaching a peak in the number around the age of 40 years and then start to decline, so at the age of 70-80 are genuine Melanocytic nevi are minimal.
The nevi beyond the aesthetic issue that can cause due to localization and size are important because of their connection with melanoma, one of the most dangerous cancers in the body. Melanoma if diagnosed early and treated effectively removed immediately, but is delayed and deepened or give metastases is poor evolution as existing treatments cannot effectively block it. Melanoma can develop on a pre-existing nevus or start in normal skin. In any case at least initial steps may seem like common nevus so important to be able to recognize some items that should motivate us.
Let’s see some basic characteristics of a suspicious mole that everyone can understand and which must lead him to the dermatologist. We will follow the internationally recognized mnemonic ABCDE rule which helps us to sort you need to check:
A (Asymmetry) asymmetry of the nevus , i.e. if divide the nevus vertical and horizontal axis (row) right to left and top to bottom are not similar to each other.
B (border) the limit in the region of nevus if has parts like fingers or lacy appearance should lead us to further control the dermatologist.
C (color) to COLOR the nevus if not uniform and had a great selection (eg one or more combinations of black, brown, gray, blue, red and white elements) must mobilize.
D (diameter) The DIAMETER of olive, if more than 5.6 mm is also considered point for investigating.
R (evolution) EVOLUTION of ABCD of the change in a relatively short time (usually months to year) is the most important element and should soon reach out to the dermatologist.
If we also see a new fault occurs, especially at a later age (after 40) and is different from the olives that we already have need to arrange examination by a specialist in a short time. Of course the appearance of melanoma exclude smaller groups so generally should not be complacent. Finally other items hit the bell of danger is if a mole starts to bleed but do not injure or taking liquid if scratching or losing our hair that was always on her and generally if changing characteristics than we had become accustomed.
How often should we check our warts.
As you are good at regular intervals (eg every 1-2 months) to check your skin or examine him / your partner or your family members to timely discover a suspicious lesion and help the doctor to further treatment. The dermatologist, having considered clinically olives will focus on many of the background and appearance seem suspect and proceed to an examination by a special lens, Dermatoscops.
If suspicious lesions are multiple will refer the patient to specialized centers for the photograph (digital mapping) and get into a periodic inspection program (every 6-12 months). If a suspicious lesion is, must be removed and sent for biopsy examination usually sets the diagnosis.
