Tinea capitis due to Trichophyton soudanense mimicking bacterial folliculitis.

We report the case of a 36-year-old Senegalese male with non-scarring alopecia of the scalp, including nodules and pustules, diagnosed as tinea capitis caused by Trichophyton soudanense. This dermatophyte is endemic in Central Africa and is becoming more frequent in Europe because of immigration. It has seldom been isolated in Italy. Tinea capitis is common in childhood and it is rare in adults, in which female sex is preferred. In adults, alopecic patches have to be distinguished from those due to other dermatoses inducing alopecia.
