Table IV.

Recommendations for management of DN

Any clinically suspicious nevus should be removed

DN should be regarded as histologic variants of CN

Beyond histologic examination, no tests currently available to predict biologic behavior of nevi

Most DN do not need to be re-excised following biopsy

DN showing severe histologic dysplasia or that cannot be distinguished from melanoma should be re-excised

Patients with clinically atypical or numerous nevi, or previous biopsies of DN, should be recognized as having increased melanoma risk

Patients at increased risk for melanoma should be carefully monitored

CN, common nevus; DN, dysplastic nevus
