1F2D.1 Malassezia folliculitis

International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2024-01

Malassezia folliculitis is caused by the invasion of the hair follicle by Malassezia yeasts. Although Malassezia yeasts are a part of the normal human microflora, under certain conditions they can cause superficial dermatological conditions. The invasion results in the development of erythematous papules, and sometimes pustules, which may be either asymptomatic or itchy. Usually Malassezia yeasts are present along with staphylococci and propionibacteria in the follicles.
