These are the signs that it is cre…See more   Sweet Syndrome, also known as acute febrile neutrophilic dermatosis, is a rare inflammatory skin disorder with systemic manifestations. Although uncommon, it is critical for primary care physicians to recognize its clinical signs and consider it during differential diagnosis—especially when symptoms rapidly follow medication changes.   This article outlines a documented clinical case and offers a comprehensive review of Sweet Syndrome, including its presentation, diagnostic criteria, treatment, and clinical significance, particularly in relation to medication-induced reactions.   Clinical Case Summary A 55-year-old female patient with a medical history of hypertension and chronic obstructive pulmonary disease (COPD) presented with erythematous, painful facial and neck lesions accompanied by low-grade fever. She had no known allergies and reported smoking approximately 10 cigarettes daily. Her regular medication regimen included:   Enalapril (6 years) Inhaled formoterol (2 years) Due to a deterioration in pulmonary function, her pulmonologist replaced formoterol with a combination of indacaterol and glycopyrronium in capsule inhaler form.   On the second day of the new therapy, the patient developed painful, reddish skin lesions on her cheeks and neck, prompting a visit to her primary care clinic. She denied recent upper respiratory infection symptoms, had used appropriate sun protection, and made no changes to her diet or cosmetic routine.   This case highlights the rare occurrence of Sweet Syndrome following inhaled bronchodilator therapy—specifically, a combination of indacaterol and glycopyrronium, which has not previously been reported in medical literature as a trigger for this condition.   What Is Sweet Syndrome? Sweet Syndrome is classified among neutrophilic dermatoses. It typically presents with: Painful erythematous plaques or nodules Sudden onset Fever Leukocytosis The lesions are often bilaterally distributed and asymmetrical, typically affecting the face, neck, upper trunk, and extremities.   Common Symptoms: Low-grade to moderate fever Painful skin lesions (papules or plaques) Fatigue or malaise Joint pain or ocular symptoms (in some cases) Diagnostic Criteria for Sweet Syndrome According to Su and Liu (1986) and updated clinical guidelines, the diagnosis is made using a combination of major and minor criteria: Major Criteria: Abrupt onset of painful erythematous plaques or nodules Histopathology showing dense neutrophilic infiltrate without vasculitis Minor Criteria (at least two required): Though rarely associated, this case introduces a potential link between inhaled long-acting bronchodilators and Sweet Syndrome, emphasizing the need for ongoing pharmacovigilance and clinician awareness.
