Common spongiotic dermatoses

This review article focuses on the spongiotic tissue reaction pattern and some of the common entities that practicing pathologists can frequently encounter in their practice. The spongiotic tissue reaction pattern is the single most common one encountered in the routine analysis of inflammatory dermatoses, and the most non-specific one as well. Spongiotic dermatoses include a very large list of disorders which are best grouped under neutrophilic, eosinophilic, miliarial, follicular and pityriasiform forms of spogiosis. The dermatoses that will be discussed under this category include contact dermatitis, eczema, pityriasis rosea, stasis dermatitis, seborrheic dermatitis and others. (C) 2017 Elsevier Inc.
