THE LESIONS shown are from the dorsal hand of a 40-year-old white man (Figure 1), dorsal foot of a 46-year-old white man (Figure 2), and dorsal hand of a 39-year-old white man (Figure 3) (size bar, 2.5 mm). All 3 lesions reveal a relatively similar pattern. The edges of the lesions have an amorphous blue appearance (similar to blue nevi); however, the center is hypopigmented. This pattern is common in sclerotic blue nevi. Theoretically, this pattern could be caused by a clone of melanocytic cells that aberrantly proliferate and differentiate in the dermis yielding hypopigmented melanocytic cells centrally and heavily pigmented cells at the margins.
