Pythriasis versicolor atypica: A difficult diagnosis

Introduction: Pityriasis versicolor is a superficial mycosis of the skin caused by Malassezia spp., a dimorphic, lipophilic yeast, which is part of the cutaneous microbiota. The most frequent topography is the trunk and is distinguished by showing plaques with fine scales on the surface, of varying shape and size that may be hypochromic, hyperchromic or erythematous, with a chronic and recurrent evolution, usually asymptomatic. The genus Malassezia, from its description, causes confusion and controversy.
