THE LESIONS shown are from the posterior aspect of the right arm of a 62-year-old white man (Figure 1), middle upper chest of a 31-year-old white man (Figure 2), and the right lower back of a 27-year-old white woman (Figure 3) (size bar, 5 mm). All 3 lesions reveal a relatively similar pattern. The edges exhibit a red-brown network pattern; centrally, the lesions have an opalescent quality with shades of gray and red. This pattern appears to be relatively uncommon compared with the other "dysplastic"/atypical nevus patterns. Presumably this pattern represents a unique genetic defect or different environmental influences during lesion development compared with other "dysplastic"/atypical nevus subtypes.
