These spores impart a greenish to silvery fluorescence when the hairs are examined under Wood's light (365 nm).In contrast, T tonsurans, the chief cause of *black dot" tinea capitis, produces spores within the hair shaft (endothrix). These hairs do not fluoresce; they are weakened and typically break easily at the follicular opening. In prepubescent children, epidemic tinea capitis is usually self-limiting.Zoophilic species may induce a severe combined inflammatory and hypersensitivity reaction called a kerion.Another manifestation of tinea capitis is favus, an acute inflammatory infection of the hair follicle caused by T schoenleinii, which leads to the formation of scutula (crusts) around the follicle. In favic hairs, the hyphae do not form spores but can be found within the hair shaft.Table :Some Clinical Features of Dermatophyte InfectionSkin DiseaseLocation of LesionsClinicalFungiTinea corporis (ringworm)Nonhairy, smooth skin.Circular patches with advancing red, vesiculated border and central scaling.
