title: Scanning electron microscope studies of solar elastosis.
abstract: Scanning electron microscope findings of solar elastosis were compared with those of normal dermis in specimens digested by hyaluronidase and by autoclaving. Solar elastosis showed amorphous masses and broad fibres with irregular shapes and sizes in specimens digested by hyaluronidase, while it showed only fibrous structures in those after autoclaving. It is suggested that the origin of solar elastosis is elastic tissue.
