Three Cases of Perforating Disorder / 대한피부과학회지

ABSTRACT

The perforating disorders comprise a group of unrelated pathologic abnormalities sharing the common characteristic of transepidermal elimination. This phenomenon is characterized by the elimination or extrusion of altered dermal substances and, in some cases, by such material behaving as foreign material. Traditionally, four diseases have been included in this group Kyrle's disease, perforating folliculitis, reactive perforating collagenosis, elastosis perforans serpiginosum. We describe three cases of perforating disorder which showed different clinical and histopathological figures.
