Patients usually present with systemic signs such as fever and elevated white blood cell counts. Though its exact cause is unclear, Sweet syndrome is thought to arise from cytokine-driven immune responses, often triggered by infections, cancers, or certain medications—including antibiotics, antiepileptics, and vaccines. Treatment with corticosteroids typically brings quick relief.
What makes this case distinctive is that inhaled medications have never previously been reported as a trigger. Differential diagnoses such as contact dermatitis, lupus, and urticaria were carefully ruled out. Why This Matters
Because Sweet syndrome is rare and sometimes associated with serious systemic illnesses, it is often overlooked during early evaluations.
This case underscores the vital role of primary care providers in recognizing unusual drug reactions, ensuring timely referral, and initiating appropriate treatment. Conclusion
This case serves as a reminder that even well-established medications—such as inhalers—can occasionally provoke rare but serious immune responses. For clinicians, being alert to sudden skin changes after a medication adjustment is crucial.
Expanding awareness of unusual Sweet syndrome triggers can improve diagnostic accuracy and lead to faster, potentially life-saving interventions.
