In the CME Quiz (May 1, 2011, page 1037), Question 7 (page 1038) gave an incorrect description of classic urticarial vasculitis. Classic urticarial vasculitis is characterized by individual wheals that last for more than 24 hours, are painful, and leave residual hyperpigmentation or purpura. The question should have read: “A patient presents with wheals that produce a burning sensation and last more than 24 hours; when resolved they leave residual hyperpigmented areas. Which one of the following is the best next step?” The online version of the quiz has been corrected.
