title: [Pityriasis versicolor and Malassezia folliculitis].
abstract: Pityriasis versicolor and malassezia folliculitis were studied clinically and mycologically. The main results were as follows: 1) The average age of pityriasis versicolor patients has gradually become higher. 2) Negative rates of Malassezia furfur after treatment were very high by direct examination but relatively low by culture. 3) Patients who were negative by culture on completion of treatment seldom recurred within 2 months. 4) We can evaluate the effectiveness of antifungal application by using Malassezia furfur as normal skin flora on the volunteer's back. 5) Malassezia furfur (orbiculare or ovale type) is detected in follicular contents of steroid acne and acne vulgaris, which makes it necessary to establish criteria for diagnosis of malassezia folliculitis.
