How can Pityrosporum fumigatus be eradicated?

Pityrosporum is a particularly stubborn type of folliculitis, and its clinical name is pityrosporum folliculitis. The symptoms of acne caused by pityrosporum folliculitis are similar and are better in adolescents and young people, but they must be differentiated during treatment so that symptomatic treatment can be given. When treating stubborn pityrosporum folliculitis, in addition to topical medications, antifungal drugs should be taken orally at the same time. Only by using both internal and external medications can the goal of eradication be achieved.

Pityrosporum folliculitis is a follicular fungal disease of the hair follicles caused by Malassezia furfur. In 1973, Potter provided sufficient evidence for the existence of pityrosporum folliculitis as a clinical and histological disease and formally named it pityrosporum folliculitis.
