Nevi and pigmented lesions
True beauty lies in the beholder’s eyes

A nevus is a common skin lesion. Any pigmented lesion must be accurately diagnosed. Nevi are more correctly called melanocytic nevi, as they are caused by a proliferation of pigmented cells or melanocytes. If they are brown or black they can also be called pigmented nevi. They are by nature benign, but can give rise to a malign melanoma. Nevi can be flat or raised, and vary in colour from skin-pink tones to dark brown or black. They are usually round or oval shaped, but sometimes assume other unusual shapes, and can vary in size from a couple of millimetres to several centimetres in diameter. One or more nevi may be present at birth (congenital nevus) but they usually appear in childhood or adult life (acquired nevus). They are classified according to the histological location of the nevus cells as follows: junctional (located between epidermis and dermis), intradermal (located in the dermis), compound (located both between epidermis and dermis, and in the dermis) and combination (nevi are present at different depths simultaneously). Dermopathologists have also given some of them the names of those who first described them – for example, the congenital nevus of Ota, and the acquired nevi of Miescher, Unna, Sutton, Meyerson etc. Nevi can usually be surgically treated with the removal of a lozenge-shaped piece of skin. Some of them (e.g. nevi of Miescher and Unna) can be removed by shaving parallel to the skin, leaving a wound that heals spontaneously.

TYPE OF TREATMENT
 Surgical removal
INFORMED CONSENT REQUIRED
Yes
LENGTH OF EACH TREATMENT
very variable, depending on the dimensions of the lesion to be removed (from 10 to 60 minutes)
NUMBER OF TREATMENTS
1
TIME BETWEEN TREATMENTS
FORME DI ANESTESIA
Generale
SIDE-EFFECTS(ALSO TEMPORARY)
moderate discomfort for the first 24 hours. Removal of stitches depends on the anatomical position of the removed lesion (from 5 to 15 days). Very rare infections are treated with antibiotics. In the case of removal by shaving or CO2 or Erbium laser, the wound is medicated with antibiotic ointment until it heals (6-10 days) and UV ray exposure must be avoided
PRECAUTIONS BEFORE TREATMENT
No anticoagulant or antiaggregant drugs (e.g. aspirin)
PRECAUTIONS AFTER TREATMENT
avoid sun exposure
