Malassezia infections

Clinical presentation

Malassezia has seven different subspecies that cause or contribute to a spectrum of conditions including pityriasis versicolor seborrhoeic dermatitis, atopic dermatitis, infantile acne and malassezia folliculitis, with M. globosa and M. furfur the most common species isolated, particularly from HIV patients .[77][78] Malassezia   can  present  in  the  setting  of  HIV  as  pruritic pustules,  macules  or  papules  on  the  face,  chest,  back  and shoulders.  Due to its morphology and distribution it may be confused with acne vulgaris. However, malassezia folliculitis does not show comedones on the skin, which helps to distinguish it from  acne vulgaris.[79]
