A 6-month-old girl presents with a two month history of a rash
in her diaper area. Past medical history is unremarkable.
Her mother has tried using over the counter barrier creams and
antifungal medications for the past four weeks without improvement.
Her parents state that she has occasionally been feverish to 39°C
over the past month, but attributed this low grade fever to an
upper respiratory infection.
On examination, you notice the rash in the photograph above. She
also has diffuse scaling of the scalp and appears fussy.
Which of the following diagnosis are the most appropriate?
