How does mole form

First, there are many types of nevi, so there are various reasons for the formation of the system. Generally speaking, it is caused by melanin.

The second reason is that junctional nevus can be seen at birth, but it is common after 2 years old. Clinically, it is light brown to dark brown flat spots with diameters ranging from several millimeters to several centimeters. It is smooth and hairless, and can occur in any part of the body. When it occurs in palms, soles or scrotum, it is mostly junctional nevus. In adulthood, some borderline nevus become mixed nevus or intradermal nevus, but some remain flat.

The third reason is that mixed nevus cells nest in the epidermis and dermis. The nevus cells in the upper dermis are cubic in shape, rich in cytoplasm and contain varying amounts of melanin particles. The nevus cells in the middle of dermis are small, with less cytoplasm and melanin, usually nest like and clear boundary.
