[Kogöj's spongiform pustule; ultrastructural results].

The authors demonstrate, with the help of electron microscopy, the location of the polymorphonuclear neutrophils and of the keratinocytes in the Kogöj's pustule. Unlike to the classical ideas, the polymorphonuclear neutrophils are not located in the epidermal cells but in the intercellular spaces. The lesions of keratinocytes, the content of the spaces and the histogenesis have been studied. The results of this study are compared to thoses formed in the literature.
