DRESS (Drug Reaction With Eosinophilia and Systemic Symptoms) Is More: A Rare Case of Acalculous Cholecystitis

Acalculous cholecystitis is an uncommon cause of cholecystitis. Drug reaction with eosinophilia and systemic symptoms is a complex syndrome that is induced by medications with delayed manifestations. Commonly implicated medications include anticonvulsants and antibiotics. We present the first case of acalculous cholecystitis due to quetiapine-induced drug reaction with eosinophilia and systemic symptoms. This case report emphasizes the need for high clinical suspicion to initiate appropriate treatment.
