[Histopathological study on the course of a dermatophytic disease].

Histological study of cutaneous biopsies of an algerian girl with a "dermatophytic disease" (cf. supra Marill and al.). During the six first years of evolution diagnosis of mycosis had not been made for no specific fungus staining was done, but the fungus was present in the tissues. Vesicular forms and few filaments were seen in the first biopsies but polymorphism increased with the time and filaments became predominant and very abundant at the end of the disease.
