Pityriasis rosea following influenza (H1N1) vaccination

Pityriasis rosea is a distinct papulosquamous skin eruption that has been attributed to viral reactivation, certain drug exposures or rarely, vaccination. Herein, we reported a clinicopathlogically typical case of pityriasis rosea that developed after the H1N1 vaccination. With a global H1N1 vaccination program against the pandemic H1N1 influenza, patients should be apprised of the possibility of such rare but benign skin reaction to avoid unnecessary fear. Furthermore, a brief review of the current reported skin adverse events related to the novel H1N1 vaccination in Taiwan is presented here.
