What should be kept in mind when treating adult patients?

Tinea capitis is less common in adults, but its incidence is on the rise. From a diagnostic perspective, one should be on the lookout for pathogens that are rather atypical for the disease in children (e.g., T. rubrum), as well as consider “side-cut” tinea capitis (caused by T. tonsurans), which occasionally occurs after a haircut at a barbershop. For oral treatment of adults, the antifungal medications terbinafine, itraconazole, or fluconazole are options.
