Koebner phenomenon was first described almost 150 years ago as an appearance of psoriatic lesions on an uninvolved skin as a result of trauma. Since then, a large number of triggering factors taking part in its development have been reported. This study presents a patient with an unusual, not presented before cause of the Koebner phenomenon in a waist area following physical activity in a form of hula-hooping.
