A 74-year-old psychotic female patient who was treated with clozapine developed Sweet's syndrome followed by agranulocytosis from which she later died. A link between these two conditions seems unlikely. Sweet's syndrome is characterised by an acute onset of fever, leukocytosis and erythematous plaques with dense neutrophilic infiltrates. Frequent counting of the numbers of neutrophiles is advisable when skin disorders appear during treatment with clozapine.
