Cutaneous necrosis and calcinosis following electroencephalography.
The authors report 2 children who developed circumscribed dystrophic calcifications at the site of electrode placement after electroencephalographic examination. Deep cutaneous necrosis was a prominent clinical feature. A biopsy showed focal dermal calcification confirmed by a diffractometer analysis of a calcific granule. Cutaneous calcinosis is a possible risk of the usage of an electrode paste containing calcium chloride. Prolonged exposure and damaged skin seem to be prerequisites for this uncommon but harmful condition.
