A diagnosis of melanocytic proliferation was reported in almost 25% of skin biopsies, according to results of a large population-based study.

Researchers conducted a natural language processing-based analysis of electronic medical records for patients at a single health care system in the United States between Jan. 1, 2007 and Dec. 31, 2012. They aimed to determine frequency and distribution information for histologically confirmed lesions among 80,368 biopsies performed on 47,529 patients.
