A dysplastic nevus, (or naevus; pl. nevi or naevi) is an atypical mole; a mole whose appearance is different from that of common moles. Dysplastic nevi are generally larger than ordinary moles and have irregular and indistinct borders. Their color frequently is not uniform and ranges from pink to dark brown; they usually are flat, but parts may be raised above the skin surface. Dysplastic naevus can be found anywhere, but are most common on the trunk.

Cancer

---

According to the National Cancer Institute, doctors believe that dysplastic nevi are more likely than ordinary moles to develop into a type of skin cancer called melanoma. Because of this, moles should be checked regularly by a doctor or nurse specialist, especially if they look unusual; grow larger; or change in color, outline, or in any other way.

Biopsy

When an atypical mole has been identified then a biopsy takes place in order to best dignose it. Local anesthetic is used to numb the area before the mole is cut off the patient and sent to a lab to be viewed by a specialist.
