Tinea capitis: focus on African American women.

Tinea capitis is a common cutaneous fungal infection in US school children, but adults may be carriers of tinea pathogens in the scalp. However, few cases of actual tinea capitis in adults have been reported in the literature. A retrospective analysis of all adult patients with positive scalp fungal cultures from June 1997 to March 2000 were reviewed. Seventy-nine cases of tinea capitis were identified. Nine (11.4%) were adults, 7 of whom were African American women, who were an average of 46 years old (range, 25 to 64 years). Three of these patients had prior exposure to a child with tinea capitis. These results suggest that tinea capitis affects adult African Americans, particularly women. Widespread scalp culture is indicated for papulosquamous disease and alopecia in this segment of the population.
