How would you treat it?
Tinea corporis often presents as classic ringworm, i.e. annular plaques or plaques with accentuated polycyclic margin. Tinea incognito describes the results of a dermatophyte infection treated with topical steroid – extensive, non-scaly irregular patches or plaques with a tendency to follicular pustule formation.
The choice of topical or systemic antifungal agent will depend on extent and duration of infection.
