A fatal case of generalized amoebiasis due to a protozoon closely resembling, if not identical with, Iodamoeba bütschilii

A Japanese soldier, aged 22, captured in New Guinea, died 7 weeks later from generalized amoebiasis. There were amoebic ulcers in stomach, small intestine, caecum, ascending and transverse colon, as well as metastatic amoebic foci in gastric and mesenteric lymph nodes, both lungs and the brain. The causative amoeba was either Iodamoeba bütschlii or one closely resembling it.
