Sclerotic Blue Nevi

Arch Dermatol. 2003;139:1522.

	Since this article does not have an abstract, we have provided the first 150 words of the full text and any section headings.

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.
