    Abstract:
    INTRODUCTION: Drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe toxidermia that can lead to death from multivisceral failure. We report a case of DRESS associated with febrile agranulocytosis in a child. OBSERVATION: An 8-year-old child was hospitalized for diffuse maculopapular exanthema with edema of the extremities and face associated with cheilitis and febrile agranulocytosis. This symptomatology began 1month after the introduction of carbamazepine for partial epilepsy. The clinical picture was a multisystemic disease with colitis, interstitial pneumonitis, hepatic cytolysis, and hepatocellular insufficiency. HHV7 viral reactivation and increased eosinophils (20%) in the myelogram were demonstrated, providing the diagnosis of DRESS. The progression was favorable after carbamazepine therapy was stopped and systemic corticosteroids were administered. DISCUSSION: DRESS syndrome is a disorder that is unfamiliar to pediatricians. Its association with agranulocytosis is rare and the absence of hypereosinophilia contributed to diagnostic difficulties in this case. The multisystemic failure, the reactivation of HHV7, the increase of eosinophils in the myelogram, and the favorable progression under systemic corticosteroid therapy contributed greatly to the diagnosis. A cutaneous biopsy was not considered necessary for the diagnosis in the case reported herein. CONCLUSION: DRESS syndrome is rarely associated with agranulocytosis, but its diagnosis must be quickly raised so that the incriminated drug can be interrupted.
