Acute generalized exanthematous pustulosis (AGEP) is characterized by acute nonfollicular sterile pustules on a background of edematous erythema. Hydroxychloroquine (HCQ), an antimalarial drug, widely used to treat rheumatic and dermatologic diseases. HCQ has been reported to be an uncommon cause of AGEP. We report a 60-year-old woman with rheumatoid arthritis requiring the use of HCQ presented fever and erythematous eruption on the trunk with sterile pustules. Leukocytosis and elevated erythrocyte sedimention rate noted on laboratory examination. On the histopathological examination of the skin biopsy specimen showed neutrophilic infiltration and scattered eosinohpils. The lesions were resolved with removal of HCQ. The clinical course was consistent with the diagnosis of AGEP associated with HCQ. We reported a case of typical AGEP associated with HCQ in a patient with Rheumatoid arthritis. The patient presented resolution from cutaneous lesions with withdrawal of culprit drug, without the need of systemic steroid.
