The case of a 56 years old man is presented, who developed acute generalized exanthematous pustulosis 5 days after the introduction of olanzapine 10 mg. Multiple 1-mm pustules appeared on the whole body, concentrated especially on her neck and face. Within 2 days, the eruption was increasingly accompanied by erythema and pruritus. No fever, chills, nausea, vomiting, arthralgias or myalgias were recorded. The diagnosis was corroborated by hystopathology. After 7 days of treatment, olanzapine and valproate were stopped. Concomitantly, cetirizine 20mg p.o. and methylprednisolone 500 mg i.v. were given once. During the following week betamethasone cream was applied, and the pustular eruption resolved completely.
