Mole – Nevus

The cells that give the skin color and are melanocyte are types of nerve cells and they migrate towards the skin during the early months of the organ development period. If the cells are not correctly scattered at their destination point, they show accumulation in different skin layers. They are named according to where they are located. Dermal nevi are located under the skin tissue, junctional nevi are located on top of the skin tissue, and compound nevi are located in every part of the skin tissue. Approximately 200 moles are seen on each person. Hereditary reasons and environmental factor alterations, there is a risk of the nevus becoming malignant. In people with risk, the body’s mole map should be mapped and followed every 6 months – 1 year. Dysplastic nevi are differences seen in cellular surfaces. Dysplasia can be seen when color impairment, side irregularity, and due to thickness of the skin thickness. If there are abnormalities such as growth, color changing, incrustation, bleeding, or other sensibilities, the mole should be wholly removed and sent to histopathology if possible. Congenital melanocytic nevus (seen during birth or in the first months after birth) is seen 2.5% in newborns but only 1% of these is real nevi. Big congenital nevi are 6.3% and small congenital nevi are 5% likely to turn malignant. For this reason, congenital nevi should be removed wholly if possible. If it cannot be removed, it should be followed up and protected from the sun. Hollow nevi, in a ring shape that are seen are due to middle cell destroyment. Spitz nevus is seen on the skin as elastic, swollen masses. Blue nevus is 0.5% seen in White people. The ones those are bigger than 10mm should be treated. Mongol spots are seen amongst Mongolian people in newborn babies (by their coccyx) in blue-grey color. It gets less after birth by age 7 and then takes an indefinable condition. Ota nevus can be seen near or inside the eye. Ito nevus can be seen on the shoulder or on the front side of the shoulder. Pigment hairy epidermal nevus (Becker’s nevus) is seen near the breast area in different hairy, colored lesions. It can also spread to the arms and legs.
