Rash. Pityriasis rosea presents first as a single large pinkish-red patch. Generally, about 1-2 weeks later, a more diffuse rash develops in a "christmas tree" distribution along the lines of skin tension. Usually, each red patch has a round area of scaliness within the borders of redness. It can occasionally be itchy.
