Question How would you diagnose a fungus with numerous microconidia and macroconidia

A 4-year-old boy was taken by his mother to the family doctor for evaluation of a 2-month history of a slowly growing "bump" on the back of his head. The boy had no other siblings nor any pets at home. He attended a day care center weekdays while his mother worked. Examination revealed a happy, alert child in no distress. A raised, scaling lesion 3.5 cm in diameter with a few pinpoint pustules was present on the posterior scalp. A KOH preparation of material from the lesion was negative. A fungal culture of material from the lesion was later positive for a fungus with numerous microconidia and macroconidia typical of Microsporum species.

What additional examination might have revealed this infection while the child was in the doctor's office?
A. X-ray
B. Serologic test
C. Ultraviolet light
D. Biopsy
E. DNA probe
