pathologic correlation is essential as several disease entities may appear indistinguishable histologically and yet be clinically distinct. Many of these disorders present with vesicles or bullae in their early or acute forms. Epidermal spongiosis is one mechanism by which intraepidermal vesicles are formed. In general, the spongiotic dermatoses can be divided histologically into a spectrum of acute, subacute, and chronic forms (Table 3). Clinicopathologic Correlation: Clinical Feature
