RÉsumÉ
Les auteurs rapportent une observation d’hypobêtalipoprotéinémie homozygote caractérisée par un tableau clinique de stéatorrhée et une absence d’apolipoprotéine B. L’æsogastro-duodénoscopie permet de retrouver un aspect jaunâtre, neigeux d’infiltration graisseuse qui oriente le diagnostic. Les biopsies pratiquées dans le même temps permettent les études histologiques en microscopie optique, électronique et en immunofluorescence qui confirmeront le diagnostic.
Summary
The authors report a case of homozygote hypobetalipoproteinemia presenting with steatorrhea and an absence of apolipoprotein B. Esogastroduodenoscopy shows a whitish snowlike appearance of fatty infiltration which orients the diagnosis. Biopsies taken during endoscopy undergo histological study using light and electron microscopy as well as immunofluorescence which confirms the diagnosis.
