“…A slow increase in cases due to T. tonsurans occurred in the 1940s and 1950s in certain states in the United States. For example, a survey from Texas noted that the incidence of tinea capitis due to T. tonsurans was 13% in 1936–1937, 20.3% in 1947–1951, and 75% in the late 1950s ( 10, 11). This organism may have been introduced into the Southwest from Mexico and Puerto Rico ( 12, 13).…”

Tinea capitis is perhaps the most common mycotic infection in children. In North America the epidemiology of tinea capitis has changed so that Trichophyton tonsurans now predominates over Micro-sporum audouinii. With this transition the utility of the Wood's light for diagnosis has been reduced since T. tonsurans infection is Wood's light negative. Griseofulvin has been the mainstay of therapy for the last 40 years. The newer antifungal agents-itraconazole, terbinafine, and fluconazole-appear to be effective and safe for the treatment of tinea capitis. When tinea capitis is due to T. tonsurans or other endothrix species the following regimens have been used: itraconazole continuous regimen (5 mg/kg/day for 4 weeks), itraconazole pulse regimen with capsules (5 mg/kg/day for 1 week plus 1-3 pulses 3 weeks apart), and itraconazole pulse regimen with oral solution (3 mg/kg/day for 1 week plus 1-3 pulses 3 weeks apart). With terbinafine tablets the continuous regimen (>40 kg body weight, 250 mg/day; 20-40 kg, 125 mg/day; and <20 kg, 125 mg/day) is given for 2 to 4 weeks. Fluconazole tablets or oral suspension (6 mg/kg/day) were administered for 20 days in one trial. Another possibility may be 6 mg/kg/day for 2 weeks and evaluating the scalp 4 weeks later. An extra week of therapy (6 mg/kg/day) can be administered if clinically indicated at that time. A once-weekly regimen may also be effective. When ectothrix organisms (e.g., Microsporum canis) are present, a longer duration of therapy may be required. The data suggest that the newer agents are effective, safe with few adverse effects, and have a high benefit:risk ratio. It remains to be seen to what extent griseofulvin will be superseded for the treatment of tinea capitis. Adjunctive therapies may help decrease the risk of infection to other individuals. Appropriate measures should be taken to reduce the possibility of reinfection.

The epidemiology of tinea capitis has had a remarkable change in the past 20 years. It is important for physicians to realize that most tinea capitis in the United States is caused by Trichophyton tonsurans and that these lesions cannot be diagnosed by the Wood's lamp. Trichophyton tonsurans tinea capitis is frequently misdiagnosed because the lesions mimic such common scalp conditions as dandruff and seborrhea. Further, this organism can cause chronic tinea capitis in women that may become a infectious reservoir for other family members. A negative potassium hydroxide preparation will not rule out infection with T tonsurans and cultures are necessary. Scalp lesions in children should be considered tinea capitis until culturally proved otherwise.
