Emerging inflammatory dermatoses: New entities, novel observations, and concept review of selected established conditions

Abstract

There has been relatively little change during the past four decades in the way dermatopathologists approach and interpret biopsies obtained from inflammatory skin disorders. If anything, there has been a stronger emphasis on clinicopathologic correlation as an aid to arrive at a clinically meaningful diagnosis. Nevertheless, new and novel observations made under the microscope have improved our understanding of several existing conditions and paved the way toward recognition of newer entities. This review looks at a selection of inflammatory dermatoses which are either newly recognized or where unique microscopic findings published in recent years have refined our understanding of some established conditions.
