During a mission in ex-Yugoslavia between 2001 and 2004, three French soldiers were sent home because of right pneumopathy, right pleurisy after appendicectomy, haemoptysis and liver haematoma, respectively. They previously were stationed in Africa and/or South America. The initial diagnosis was quickly modified: pleuropulmonary manifestations of amoebic hepatic abscess in two cases, and pleuropulmonary amoebiasis in the last case. The outcome was favourable with standard anti-amoebic treatment. The reports illustrate the possibility of hepatic amoebiasis with local pleuropulmonary manifestations and an exceptional case of pleuropulmonary amoebiasis with hepatobronchial fistula. The authors report this experience because it demonstrates that amoebiasis in European countries remains an often forgotten diagnosis. Although known for a long time in developing countries, amoebiasis in the military or in tourists should be systematically considered.

Entamoeba histolytica, is a human pathogen which is endemic in tropical areas. The most common extra-intestinal locations for disease after the liver are pleural and pulmonary. Although the outcome of pleural and pulmonary amoebiasis is generally favourable, it is important to note that a significant proportion of patients do develop pleural and pulmonary after-effects. We report a case of pleural and pulmonary amoebiasis where the evolution of a massive pleural effusion and 3 associated liver abscesses was spectacular. The surgical management of pleural, pulmonary and liver amoebiasis is discussed.

Pleuropulmonary amebiasis is a very rare complication of amebiasis infection and direct pulmonary involvement is exceptional. The clinical diagnosis is difficult without any intestinal or extraintestinal manifestations. A percutaneous drainage is necessary to aspirate pus. We report herein the case of a 56-year-old man presenting with an amebic lung abscess in his right lower lung and pleural effusion. The diagnosis was suspected by our laboratory from a serological assay (antiamebic antibodies reaching 320 by IHA) and established from a direct examination of the pus in which rare trophozoites of Entamoeba were detected. We pointed out the importance of the communication between the clinician and the biologist. Protozoan infection should be suspected in pleuropulmonary infection when antibiotics failed even in France. This patient left endemic area a long time ago and the way of his amebiasis contamination is unknown: recurrence of amebic infection is rare and prevalence in industrialized countries reaches only 1%. Several hypothesis are exposed.
