[Invasive amebiasis].

There has only a small number of invasive amoebiasis cases occurred in Hungary up to now. Introducing two of our cases we would like to call attention on these cases coming mainly from tropical countries or having been just transiently there invasive amoebiasis should also be considered. Modern diagnostic imaging technics are of importance in differential diagnosis in showing antibodies against amoebas (!) because amoebas frequently cannot be directly shown from the patients in the invasive stage. Both ulcerous amoebic colitis and amoebic liver abscesses can be treated with drugs affecting amoebas in deep tissues (metronidazole, emetine, and its derivates, etc.).
