The human body commonly exhibits congenital or acquired skin lesions such as freckles, moles, and changes in skin pigmentation. Most of these lesions are benign; however, in some cases, they can become malignant. Therefore, their progression needs to be monitored.

Malignant moles often have asymmetrical shapes. Benign moles have soft, rounded borders, but atypical moles have map-like, jagged, and irregular borders. Instead of being just brown or black, malignant moles may have areas that are darker or lighter, black, brown, red, blue, or depigmented.

Common moles are typically under 6mm in size, but moles larger than 6mm are considered risk factors.

With moles that have a risk of malignancy, the time it takes for them to grow from small to large is very short. They can increase in size several times in just a few months. In addition, there may be other characteristics such as ulceration, bleeding, a rough surface, itching, or pain.
