Case: A 10-year-old girl is brought for evaluation of an itchy, red, enlarging rash on the left eyelid. When the rash first appeared 4 weeks earlier, she presented to her pediatrician who prescribed a topical combination nystatin and triamcinolone acetonide cream. The mother applied the cream for 2 weeks and noted improvement in the redness initially; however, over the next 2 weeks, the lesion persisted and rapidly enlarged.
The 5-cm, well-demarcated, erythematous, annular, scaly plaque involves the entire left eyelid and extends onto the nasal bridge. Physical examination findings are otherwise normal.
Why did this rash persist and worsen despite treatment?
