A routine medication change led to a rare complication when a 55-year-old woman developed painful red skin lesions and fever shortly after starting a new inhaler.
Within 48 hours, symptoms appeared on her face and neck, prompting urgent evaluation. Doctors stopped the medication and ran tests, ruling out infection and other causes.
A biopsy confirmed Sweet syndrome, a rare inflammatory condition—making the case notable as a possible link to inhaled respiratory treatment.
