Tissue affected by this disease may be surrounded by pale rings named for Woronoff and shows Munro microabscesses and elongated thin rete (“ree-tee”) ridges.

For 10 (10[2])points, name (10[1])this skin (10[1])disease that causes (10[1])itchy (10[1])red plaques (10[4])with (10[1])silvery scale. (10[1])■END■ (10[1])
