Pityriasis rosea: Appearance and distribution of macules aid diagnosis

A 40-year-old man presented with a 1-week history of a diffuse pruritic rash. The patient denied having had fever, chills, or a recent respiratory infection. He could not recall having an initial patch. Physical examination revealed numerous small, scaly patches on his trunk (figure 1 ). The rash spared the palms of his hands and soles of his feet as well as the distal extremities.
