Congenital melanocyte nevus are benign overgrowth of skin melanocytes that occur as a result of abnormal growth, development or migration of melanoblasts. Affecting approximately 1% of newborns, congenital melanocytic nevus forms between 5 and 24 weeks of gestation and is present at birth or becomes apparent during the first year of life.1 The appearance of congenital melanocytic nevus varies considerably depending on the morphology, texture, location and size. The nevus can be round or oval with smooth, well-defined edges, and the surface texture can be papular, rough, warty, or cerebral. Congenital melanocyte nevuses can be distinguished from histologically acquired nevus, since the nevomelanocytes of congenital melanocyte nevuses are unique and extend under the surface of the skin, can spread to the deep dermis and can also exist in the fat beneath -cutaneous, fascia or muscle .2 Although initially a nevus may be light, flat or hairless, it may become more pigmented, raised and acquire long, coarse hair. Although they can appear anywhere on the body, the most common anatomical location for a giant congenital melanocytic nevus is the posterior trunk, followed by the legs, arms, head and neck.3
Clinically, congenital melanocyte nevuses are classified according to their size. Small nevuses are generally considered to be less than 1.5 cm in diameter the largest, medium nevus between 1.5 and 19.9 cm in largest diameter, and large or giant congenital melanocytic nevus 20 cm or more larger in diameter.2 In addition, because the growth of these lesions being proportional to the overall growth, a more precise definition of the giant congenital melanocytic nevus compares the size of the lesion to the total body surface; lesions that occupy 2% or more of the body surface are classified as giant nevus. Giant nevus often have distributions of "bath trunks" and "glove storage" and can appear with several smaller satellite lesions.
