Acute generalized exanthematous pustulosis caused by sulfasalazine

Abstract

In the landscape of cutaneous adverse drug reactions (cADRs), acute generalized exanthematous pustulosis (AGEP) remains a pertinent dermatological manifestation. This research delineates a clinical presentation consistent with AGEP precipitated by the administration of sulfasalazine in a 68-year-old female. Drawing from the EuroSCAR study’s diagnostic parameters, the patient exhibited salient features such as facial erythema and a pervasive papular rash, concomitant with specific hematological perturbations, including leukocytosis and elevated hepatic enzymes. Utilizing the EuroSCAR AGEP validation score, a definitive diagnosis was ascertained, obviating the need for histological confirmation. Subsequent therapeutic interventions facilitated symptomatic resolution, leading to the patient’s discharge with a categorical advisory against future sulfasalazine exposure. This elucidation accentuates the causative potential of sulfasalazine in AGEP manifestation and underscores the imperativeness of vigilant diagnosis and timely intervention.
