One hundred and twenty-six cases of pityriasis rosea seen over two years in north Staffordshire were analysed for clustering in time and space. A statistically significant degree of clustering was found; this was evident among female patients considered separately but not among male patients. The incidence of the condition was higher in patients working in, or attending, educational establishme...

Dear Editor-in-Chief   Lesional histopathological features in pityriasis rosea (PR) are non-specific (1).  Our aim here is to investigate whether a histopathological take-off sign (TOS) is associated with PR.

Pityriasis rosea is a distinct papulosquamous skin eruption that has been attributed to viral reactivation, certain drug exposures or rarely, vaccination.

With a global H1N1 vaccination program against the pandemic H1N1 influenza, patients should be apprised of the possibility ...

Pityriasis rosea (PR) is a common skin eruption in children that is characterized by a single skin patch that usually evolves into a widespread exanthem after one week. The duration of PR is typically six weeks and the condition is selflimited with excellent prognosis. The diagnosis is established by proper history taking and physical examination of the skin lesions. Laboratory investigations a...
