The article “Diagnostic Approach to Polyarticular Joint Pain” (September 15, 2003, page 1151) incorrectly stated in Table 4 that inflammation of the earlobe is a sign of relapsing polychondritis. The earlobes are spared in relapsing polychondritis, because the rare condition affects cartilage and earlobes do not contain cartilage. Therefore, the article should have stated that inflammation of the ear, sparing the earlobe, is a sign of relapsing polychondritis. The online version of this article has been corrected.
