Sorry for late reply Brian.. Reason detailed in pm... You condition does look like pityriasis rosea to me too. But the pic is not quite clear.. Other possibility could be parapsoriasis... But the way of presentation and its morphology suggest pityriasis rosea.. Anyway do u have such lesions on chest and back? Were you on any medications recently? any recent history of illness and do you have such lesion on groin? If its bothering you you may apply mild steroids lotion to ease the lesion and itching.. PR is not contagious you needn't worry...
