[Severe forms of imported malaria concerning three pernicious attacks and a black water fever (hemoglobinuria)...

Four severe cases of imported malaria are reported here. Three of them are pernicious and the fourth is a black water fever (hemoglobinuria). The difficulties of initial diagnosis are exposed. There was no mortality in these four cases which represent the annual recruiting of a multipurpose intensive care unit. But the complications are severe in contradiction with easy effective chemoprophylaxis. The principles of treatment and prophylaxis are resumed in the light of these four observations.
