also known as atypical moles, are moles that have an abnormal appearance and are often larger than normal moles. They may have irregular borders, uneven color, or a mixture of colors. Dysplastic nevi can be a risk factor for developing melanoma, a dangerous type of skin cancer, and should be monitored by a dermatologist. Treatment for dysplastic nevi typically involves monitoring the mole for changes and removing it if necessary. If your dermatologist determines that a dysplastic nevus has a higher risk of becoming cancerous, they may recommend removing it surgically and having it examined under a microscope. Additionally, if you have a history of dysplastic nevi or other risk factors for skin cancer, your dermatologist may recommend regular skin exams to monitor for any changes in your skin.
