บทคัดย่อ

The HLA-B*58:01 allele is associated with severe cutaneous adverse reactions, including Stevens-Johnson syndrome, toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms, and maculopapular eruption. We describe the case of a 58-year-old male who developed non-follicular pustules on the back and flank, along with erythematous papules on the trunk and both upper and lower extremities after taking allopurinol for 2 weeks. Histopathological evaluation confirmed a diagnosis of acute generalized exanthematous pustulosis (AGEP). Genetic testing revealed HLA-B*58:01 positivity. To our knowledge, this is the first reported case of AGEP associated with HLA-B*58:01 in the context of allopurinol-induced hypersensitivity.
