Pityriasis rosea is an acute inflammatory dermatosis, probably infective in origin, with a self- limiting course, affecting mainly children and young adults. Most of the patients have only single attack. We are reporting a patient with recurrent pityriasis rosea who had 5 attacks in last 4 years.

Each episode lasted for 4-6 weeks. In each episode a herald patch on left scapular region first appeaared which was followed by a secondary eruption.

| Discussion|| |
Pityriasis rosea is a relatively common disease with the highest incidence in the autumn, winter and spring. Only a few reports are available regarding recurrent pityriasis rosea.,,, Second attacks of pityriasis rosea are said to occur in about 2% of cases after an interval of a few months or many years. Multiple recurrences have rarely been reported.,  This case appears to be the first such report from India.
