Supplemental figure 2 of the correlations between clinical features, dermoscopic and histopathological findings, and treatment outcomes of patients with pitted keratolysis

Supplemental figure 2 The histopathology demonstrated color alteration of the keratin with alternate light and dark columns (figure 2A and 2B). Alternate dark and light vertical bands with depressed area corresponding to the light columns (arrow) (Hematoxylin and Eosin x100 and x 200, respectively; figure 2C and 2D). Depressed area with empty space represented the pit with cluster of bacteria along the side and at the bottom of the pit (figure 2C, Hematoxylin and Eosin x 400 and figure 2D, Periodic-acid Schiff x 600)
