A 26-year-old male presents complaining of a rash over
his upper trunk and arms. He is an Asian who has recently arrived in the UK.
On examination there are sharply demarcated depigmented
macules over the upper trunk and arms with fine scaling. There is no loss of
sensation over the macules, no loss of sweating, no lymphadenopathy, no
thickened nerves are palpable and the patient is afebrile.
Your next line of action in dealing with this patient
would be to:
Take skin scrapings and examine them for fungi
Do a TPHA test
Take a skin biopsy
Examine a slit skin smear for acid fast bacilli
Give local treatment with topical imidazole
