Stable psoriatic plaque of the lower leg before (a) and after engraving a target area by gently rotating a 5-mm biopsy punch device (b). Dermoscopy (x10) (c) and HHS (H&E stain: x100) (d) of the target area: the capillary density was evaluated in both cases in a centered 4-mm diameter area (yellow circle) by counting the number of red dots and of dermal papillae, respectively.
