[Recurrent fever episodes in an African child: diagnostic difficulties of trypanosomiasis in France].

: A young Angolian boy who had emigrated to France at the age of 2, presented with a long history of fever. Gambian Trypanosomiasis was diagnosed with peculiar aspects: 1) evolution of adult sickness with a long hemolymphatic period (first stage) and a subacute worsening period with neurologic deficit and somnolence (second stage); 2) a possible post-transfusional contamination: the young boy, born in South Angola, a nor-highly endemic area, was transfused at the age of 10 months with the blood of a donor who was subsequently treated for Trypanosomiasis; 3) a suppurating adenopathy; 4) a predominance of IgG within the hypergammaglobulinemia while IgM are the predominant immunoglobulins in this affection; 5) a hepatic toxicity of Difluoromethylornithine.
