Summary

Malassezia species, also known as Pityrosporum are members of human cutaneous commensal flora that are known to cause benign skin conditions, such as tinea versicolor, and seborrheic dermatitis.

Tinea versicolor, commonly caused by Malassezia furfur fungus, affects the skin and causes white or light-colored patches on the body.

In seborrheic dermatitis, fungi flora trigger skin inflammation, which typically affects areas with high sebaceous activity, such as the scalp, face, and trunk. It presents with redness, scaling, and itching.
