Pityriasis rosea is a skin disease that produces oval spots
(papules) over the trunk. The rash is frequently preceded by a
"herald patch" (pictured here) lasting 1 to 2 weeks. The rash is
usually rose red to brownish red with fine scales and central
clearing. Itching (pruritus) occasionally occurs. Spontaneous
remission occurs in 2 to 8 weeks. It is probably caused by an
infectious agent, most likely a virus.
