Abstract

Since its emergence reported in April 2009, pandemic influenza H1N1 rapidly spreads among humans all over the world. Although seasonal influenza vaccination has been implicated to occasionally induce skin diseases, extremely rare cases of skin eruption following pandemic influenza H1N1 vaccination have been reported. We here present a case of Mucha-Habermann disease-like eruption following pandemic influenza H1N1 vaccination. With a global H1N1 vaccination program against the pandemic H1N1 influenza, physicians and patients should be appraised of such rare skin reactions that may be induced by pandemic influenza H1N1 vaccination.
