[Invasive amebiasis with detection of Entamoeba histolytica in rectal biopsies and liver abscesses]

A 45-years old man after having returned from Thailand was admitted to the hospital with a severe ulcerative, pyogenic colitis and multiple liver abscesses. In the endoscopically taken rectal biopsies as well as in the liver abscess aspirate gained by fine needle puncture Throphozoites of E. histolytica could be demonstrated. On the other hand stool specimens and serology were negative. The various diagnostic facilities in invasive Amebiasis are discussed. Because of the problems, which may arise from the examination of fresh stool specimens, the advantage of endoscopically gained biopsies in suspected amebic colitis is emphasized.
