    • Spongiotic dermatitis is not a specific diagnosis, but rather a form of tissue reaction to injury encompassing a number of disease entities.
    • The spongiotic tissue reaction has traditionally been divided into three histologic stages: acute, subacute and chronic.  Some authors question the utility of this classification.
    • The chronic phase is quite easy to misdiagnose, as spongiosis is minimal to absent, and it closely resembles the psoriasiform pattern.
    • Histologic features include hyperkeratosis with focal parakeratosis, hypergranulosis and psoriasiform hyperplasia (acanthosis with the rete ridges extending down to approximately the same level).
