[Pityrosporum folliculitis (author's transl)].

Pityrosporum folliculitis occurs mainly among adult males on the back and may result from antibiotic and steroid administration. The lipophilic yeasts are numerous in the papulo-pustular lesions and can easily be demonstrated in the perifollicular inflammation on histological slides. 8 new cases with typical clinicopathological features are recorded by the authors. The best results are obtained with topically applied amphotericin B or econazol.
