Answer

Acute generalized exanthematous pustulosis and anticonvulsant hypersensitivity syndrome both manifest as an acute onset of a discrete pustular eruption arising shortly after beginning therapy with various medications. Although the eruption that occurs in acute generalized exanthematous pustulosis is often differentiated from anticonvulsant hypersensitivity syndrome by having nonfollicular-based pustules, either condition can have follicular or nonfollicular-based pustules.
