Tinea capitis: current concepts in clinical practice

Abstract

Tinea capitis is a common infection, particularly among young children in urban regions. The infection often is seen in a form with mild scaling and little hair loss, a result of the prominence of Trichophyton tonsurans (the most frequent cause of tinea capitis in the United States). T. tonsurans does not fluoresce under Wood light, unlike the common tinea capitis-causing fungal organisms seen in Europe and many other countries, which emit a green fluorescence. However, T. tonsurans, like other fungi, also may less often produce an intense inflammatory reaction, which is suggestive of an acute bacterial infection.
