Each specimen was studied in two ways: 1) By staining with picrosirius red and observation under polarized light on digitized images (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>), to assess collagen density and texture under the nevus, using ImageJ software (<a href="http://rsb.info.nih.gov/ij">http://rsb.info.nih.gov/ij</a>) to measure the contrast of the grey level co-occurrence matrix, second angular momentum, entropy and anisotropy, and 2) By conventional immunohistochemical methods, for its PRAME (Mab EPR20330; Abcam, #219650) expression, according to the method by Googe et al.<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">5</span></a> For statistical analysis, the software used was the SAS System for Windows.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia></span><span id="sec0010" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0010">Results</span><p id="par0015" class="elsevierStylePara elsevierViewall">Nine of the fifteen patients were female, eight had a previous history of CM at some point in their life, 51/56 DN were diagnosed up to 40 years of age, and no lesion recurred after excision.
