Features of tinea capitis caused by Trichophyton violaceum and Trichophyton soudanense

Background: Tinea capitis is a common dermatophyte infection in children. Pathogens responsible for tinea capitis vary across different geographic regions. The most common pathogens in the USA have been Trichophyton tonsurans accounting for greater than 90% of infections followed by Microsporum canis. Other pathogens such as Trichophyton violaceum and Trichophyton soudanense are common in Africa but have been rare causes of tinea in the USA. However, their incidence has been increasing in the USA possibly due to immigration patterns.
