Pie chart of various <a href="https://en.wikipedia.org/wiki/Differential_diagnosis" class="extiw" title="en:Differential diagnosis">differential diagnoses</a> of pigmented skin lesions, by relative <a href="https://en.wikipedia.org/wiki/Incidence_(epidemiology)" class="extiw" title="en:Incidence (epidemiology)">incidence</a> for those undergoing biopsy, and malignancy potential, from a United States population. The actual relative incidence of benign diagnoses is presumed to be substantially under-represented, since such diagnoses are often achieved without performing biopsy.
