The article “Evaluation of Palpable Breast Masses” (May 1, 2005, page 1731) contained an error in Figure 2, the diagnostic algorithm for the management of women with palpable breast masses. Under “Cyst,” the arrow from “No residual mass” should have led to “Repeat clinical breast examination in 4 to 6 weeks,” and the arrow from “Residual mass or bloody fluid,” should have led to “Is patient 40 years or older.” The online version of this article has been updated, and the corrected algorithm appears below.
