Pathologies related to abnormal deposits in dermatology: a physico-chemical approach

Although numerous pathologies are associated with abnormal skin deposits, these remain poorly described, as accurate characterization continues to present a challenge for dermatologists. Their submicrometer size well their diverse chemistry require various tools. We aim exemplify of endogenous and exogenous deposits in some selected diseases using different physico-chemical techniques. begin presentation deposits. then those our results which show variety structure, location chemical composition, obtained tools: Field Emission Scanning Electron Microscopy coupled Energy Dispersive X-ray Spectroscopy, fluorescence, vibrational spectroscopies, techniques specific synchrotron radiation. Our constitute real opportunity improve diagnosis, understand the pathogenesis many diseases, opportunities therapeutic intervention.
