Error in κ Values in: In Vivo Microscopic Features of Nodular Melanomas: Dermoscopy, Confocal Microscopy, and Histopathologic Correlates

Arch Dermatol. 2009;145(5):556. doi:10.1001/archdermatol.2009.99

Error in κ Values. In the article titled “In Vivo Microscopic Features of Nodular Melanomas: Dermoscopy, Confocal Microscopy, and Histopathologic Correlates,” by Segura et al, published in the October issue of the Archives (2008;144[10]:1311-1320), several κ values were reported incorrectly in the “Results” section on pages 1314 and 1315. On page 1314, left column, lines 10 through 13 should have read as follows: “Dots observed at dermoscopy correlated with pagetoid cells seen at RCM in 24 lesions (80%) and with histologic pagetoid spreading (κ = 0.50; P = .004).” On the same page, right column, “Dermoepidermal Junction” subsection, lines 2 through 7 should have read as follows: “The nonvisibility of dermal papillae resulted at confocal microscopy in the sudden transition between epidermal layers and dermal structures, corresponding at histologic analysis with a thin flattened epidermis overlying the tumor burden (κ = 0.50; P = .004).” Farther down, lines 13 through 19 should have read as follows: “In SSM lesions, the observation of dermal papillae at the dermoepidermal junction at RCM correlated with the presence of a network at dermoscopy (κ = 0.40; P = .005) and with the presence of elongated rete ridges (κ =0 .60; P = .004) in histologic sections (Figure 4D).”
