AbstractImmunogloblin A (IgA) vasculitis is the most common systematic vasculitis disorder characterized by leykocytoclastic vasculitis , for example, purpura with white blood cell destruction vasculitis caused by allergic mechanisms. The main symptoms of this disease are purpura, arthritis, abdominal pain, gastrointestinal bleeding, and nephritis. 　We report the case of a 66-year-old man with IgA vasculitis. He was diagnosed with hypopharyngeal cancer and underwent radio-chemotherapy at our department. On the following day, he underwent tracheotomy because of recurrent laryngeal nerve paralysis associated with cancer treatment. 　His wound infection remained after the tracheostomy, and he complained of purpura on both legs. On the basis of these clinical courses we diagnosed IgA vasculatis caused by wound infection. This case illustrates that it is important to consider the possibility of IgA vasculatis if skin eruption is observed concurrent with wound infection.
