Abstract

ABSTRACT Melanin-like pigment produced in vitro and in vivo by Malassezia yeasts has not been described before. Masson-Fontana staining confirmed accumulation of black pigment on the cell walls of l -dihydroxyphenylalaline ( l -DOPA)-cultured Malassezia species. Black pigment was also observed in cells and hyphae from hyperpigmented patient lesions with culture-confirmed pityriasis versicolor and seborrheic dermatitis.
