Evaluation of Langerhans' cells in normal and eczematous dermatitis skin by CD1a protein immunohistochemistry: preliminary findings.

abstract：:Typical pustular lesions of impetigo herpetiformis were examined by electron microscopy. In the upper layers of the epidermis degenerated keratinocytes and neutrophils lay close together and amorphous substances were seen within and outside the keratinocytes. Neutrophiles were not observed within the keratinocytes. Th...
