Entamoeba histolytica is a cosmopolitan pathogenic parasite. It is spread via the feco-oral route and, to a lesser extent, via sexual intercourse. We report a case of hepatic and intestinal amoebiasis in a 67-year-old man who had never travelled to an endemic area. Abdominal CT investigations detected two liver abscesses and chronic colitis. Positive amoebic serology and a positive PCR test for E. histolytica in the hepatic liquid and faeces confirmed the diagnosis. Curative metronidazole and tiliquinol-tilbroquinol were administered successfully. The patient had been contaminated through heterosexual intercourse with his healthy French female partner who was a carrier of the parasite. Though unusual, amoebiasis as a result of sexual transmission should be considered in non-endemic areas in people who have never travelled abroad, particularly in the presence of clinical symptoms such as liver abscesses or chronic diarrhoea.
