The clinical manifestation, histologic features, and Ki-67 staining before (A-C) and after (D-F) acitretin treatment. Arrowheads (B and C) indicate the cornoid lamella. (D) The clinical picture after acitretin treatment reveals that the hyperkeratotic ridges are diminished and the erythema inside the ridge is decreased. Arrows (E and F) indicate the border between the lesional side (L) and the nonlesional side (N). No more cornoid lamella is noted. (B and E, Hematoxylin-eosin stain; C and F, Ki-67 stain; original magnification: B, C, E, and F, ×40.)
