Rev Med Liege 2016, 71(6),298-301Abstract : Toxic epidermal necrolysis (TEN, Lyell syndrome) is a severe paroxystic drug reaction whose inductive mechanisms remain poorly understood. The HLA glycoproteins are possibly involved in the disease process. Such investigations rely on biomolecular methods, and suggest specific interactions between some drugs or their metabolites and some HLA groups according to ethnicity of the TEN patients. Electron microscopy following the immunogold method for revealing HLA-DR did not disclose any evidence for distinguishing distinct patterns on Langerhans cell membrane between the initial and the resolution phases of TEN.
