I enjoyed Dr Kirk Barber’s interesting Dermclinic quiz featuring a 5-year-old boy with a dramatic resentation of tinea corporis (CONSULTANT FOR PEDIATRICIANS, February 2009, page 43). I am curious to know why Dr Barber prescribed oral terbinafine for this patient.

I am curious to know why Dr Barber prescribed oral terbinafine for this patient. I was taught to reserve oral antifungals for the treatment of onychomycosis or tinea capitis but to use topical antifungals for other purposes.

In my experience, when tinea corporis is extensive, the best way to treat it is with a systemic agent. Otherwise, you often wind up “chasing” the infection from area to area and find it difficult to obtain a cure. In addition, in extensive tinea corporis, the hair follicles have likely been invaded, and much as in tinea capitis, topical therapy will not penetrate to the site of infection.
