[Mixed dermatophytic infection of the hairy scalp].

A mixed infection induced by Microsporum canis and Trichophyton tonsurans has been observed on the scalp of a 10-year-old girl. Microscopy has shown microsporum-type endo-ectothrix parasitism on some hairs, whereas others exhibited a strictly trichophyton-type endothrix parasitism. This double parasitism was confirmed histologically (PAS coloration), and M. canis and T. tonsurans could be cultured. The infection was eradicated after 5 weeks of treatment with griseofulvin (750 mg/day per os) and local application of 1% Econazol spray solution twice a day.
