Error in lesion size. The Photo Quiz “Pigmented Lesion on the Sole in a Child” (July 15, 2013, p. 135) contained an error in the first sentence of the second paragraph (p. 135). The lesion measured 7 mm, rather than 0.7 mm; therefore, the sentence should have read: “Physical examination showed an asymptomatic brown lesion measuring 7 mm (see accompanying figure).” The online version of this Photo Quiz has been corrected.
