Moles

A mole, also known as melanocytic nevus, is a benign skin lesion caused by local increases in pigment cells. Moles can be present at birth or appear later in life. There are many different types of moles, and almost everyone has at least one mole. Lighter skinned people generally have more moles than darker skinned people. The exact reason for developing moles is unknown, but the number of moles a person has is dependent on genetics, sun exposure, and immune status.

What are the features of moles?

• Arise on any part of the body
• Differ in appearance based on body site
• Flat or protruding
• Vary in color from pink, flesh, dark brown, steel blue, or black
• Round or oval shaped
• Range in size from a couple of millimeters to several centimeters in diameter

A dermatologist can diagnose a mole based on the clinical appearance. If your dermatologist has any concerns about the mole, a skin biopsy might be taken and sent to evaluation with a dermatopathologist to rule out skin cancer. If a mole is irritated or you are not happy with the appearance of a mole, your dermatologist can pursue cosmetic treatments such as shave removals, electrodessication, or excisions to remove the mole. Appearance of new moles can be slightly minimized with strict sun protection, but it is unlikely to make a significant difference.

If you would like a skin exam to assess your moles or have noticed new or changing moles you would like assessed, our dermatologists can evaluate your skin and discuss any potential treatment if necessary.
