We reported a case of multiple organ dysfunction syndrome (MODS) following about 300 wasp stings.The diagnosis was based on autopsy findings of acute pulmonary edema,acute kidney injury,hepatic and cardiac dysfunction,and cerebral edema.MODS is a life-threatening complication,and should be considered a possibility after multiple wasp stings.Our autopsy helped to establish the cause of unexpected death due to wasp stings and to elucidate a possible mechanism of MODS.
