Elevated phosphorus in psoriatic skin determined by energy dispersive x-ray micro-analysis

Scanning electron-microscopy in combination with secondary electron imaging and x-ray energy spectrometry (electron-probe micro-analysis) was performed on the stratum corneum of involved and uninvolved, psoriatic skin. The significant, elemental alterations included an increase in phosphorus and calcium in the involved skin regions. A composite, chemical, elemental profile of normal and uninvolved, psoriatic stratum corneum is presented.
