Year: 2025
Type: article
Study design: Case Report
Abstract: Background: Generalized Bullous Fixed Drug Eruption (GBFDE) is a severe cutaneous adverse drug reaction that can mimic toxic epidermal necrolysis (TEN).Its prompt recognition is crucial to prevent severe complications and recurrence upon drug re-exposure. Case ReportCase Report: We report the case of a female patient in her fifth decade who developed widespread bullous lesions with significant epidermal detachment within 24 hours of taking Piroxicam.A previous, less severe reaction to Diclofenac was noted, suggesting cross-reactivity among NSAIDs.Given the potential severity of GBFDE and its risk of recurrence, accurate diagnosis and strict drug avoidance strategies are essential, along with hemodynamic management and the use of topical or systemic corticosteroids.Conclusion: This case highlights the importance of thoroughly reviewing patients' allergy history and considering a complete switch to a different pharmacological class, especially in cases of lifethreatening hypersensitivity reactions.
