The question
A dermatology resident is taught about dermatophyte infections. Consider four statements: 1. KOH mount from the active edge of the lesion shows septate branching hyphae. 2. Some Microsporum species infecting the scalp fluoresce green under Wood's lamp. 3. Nail infections need a longer course of treatment than infections of glabrous skin. 4. Dermatophytes commonly invade the blood and spread to internal organs. Which statements are correct?
